Chebyshev Filter : Design of Low Pass and High Pass Filters
 
22:11
In this video, you will learn, how to design Chebyshev low pass and high pass filters using OP-Amp. In this video, you will learn, how to interpret the Chebyshev filter design table and using that how to design the Chebyshev filters using Salen-Key filter topology. Chebyshev Filter: Chebyshev Filter provides the faster roll-off than the Butterworth filter. But it has ripple in the passband. Four important parameters for Chebyshev Filter Design: 1. Passband Ripple (Ap) 2. Passband Cut-off Frequency (wp) 3. Stopband Cut-off Frequency (wc) 4. Stopband Attenuation (As) What is filter table: Filter table is very useful tool for designing filters, in which coefficients of the filter polynomials and different parameters like Q value, Frequency Scaling factor are given for different order of the filters. So, in this video, by taking one filter design example it has been shown that the same transfer function can be achieved if the filter design is designed using filter table and mathematical equations of Chebyshev Filter.

Filter Approximations: Overview of Butterworth, Chebyshev, Elliptic and Bessel Filter Approximation
 
09:53
In this video, five different types of filter approximations which are quite commonly used in the analog filter design have been discussed briefly. What is Filter Approximation: Ideal filters have brick wall type of frequency response. So, they have flat passband and monotonic stopband. And the transition from passband to stopband is very abrupt (vertical transition). But in actual filter design, it is almost impossible to achieve frequency response like an ideal filter. So, in filter design (particularly for higher order filter design), five different types of filter approximations are quite commonly used. 1. Butterworth Filter Approximation 2. Chebyshev Filter Approximation 3. Inverse Chebyshev (Chebyshev Type-II) Filter Approximation 4. Elliptic Filter Approximation 5. Bessel Filter Approximation 1. Butterworth Filter Approximation This filter approximation is also known as the maximally flat response approximation as it provides the flat passband response. It does not have any ripple in the stop band and the roll-off rate is 20n dB /decade. It is most often used in audio processing applications where flat passband response is necessary. 2. Chebyshev Filter This filter has rippled passband and monotonic stopband, but the roll-off rate of this filter is faster than the Butterworth filter. It is also known as the equal ripple filter. 3. Inverse Chebyshev (Chebyshev Type -II) Filter Approximation This filter has flat passband and rippled stop band, and the roll-off rate is same as the Chebyshev filter. 4. Elliptic filter approximation This filter has rippled passband and stopband but it has fastest roll-off rate among all the filter approximations. While it has very poor step response. 5. Bessel Filter Approximation This filter has flat passband and monotonic stop band like Butterworth filter but the roll-off rate is slowest among all the filter approximations. This filter has linear phase to frequency response, and hence very good step response. Here are the timestamps for the different topics in the video: 0:48 What is Filter Approximation? 3:10 Butterworth Filter Approximation 4:04 Chebyshev Filter Approximation 5:13 Inverse Chebyshev Filter Approximation 6:07 Elliptic Filter Approximation 6:40 Bessel Filter Approximation 7:51 Comparision of different filter approximations This video will be helpful to all students of science and engineering in understanding the concept of filter approximation and to get the overview of different filter approximations.

Understanding frequency selective services requires specific domain knowledge. This video provides an overview of filtering basics beyond just know if your filter is low-pass, band-pass, high-pass, or notch. How quickly does it roll off? How far into the stop band does my Nyquist criteria need to be? Why would I accept ripple in my filter? Is my attenuation enough?

Pi filter Ripple calculations.
 
06:28
Electronic filters are circuits which perform signal processing functions, specifically to remove unwanted frequency components from the signal, to enhance wanted ones, or both. Electronic filters can be: Three-element filters can have a 'T' or 'π' topology and in either geometries, a low-pass, high-pass, band-pass, or band-stop characteristic is possible. The components can be chosen symmetric or not, depending on the required frequency characteristics. The high-pass T filter in the illustration, has a very low impedance at high frequencies, and a very high impedance at low frequencies. That means that it can be inserted in a transmission line, resulting in the high frequencies being passed and low frequencies being reflected. Likewise, for the illustrated low-pass π filter, the circuit can be connected to a transmission line, transmitting low frequencies and reflecting high frequencies. Using m-derived filter sections with correct termination impedances, the input impedance can be reasonably

DSP: Using an FIR filter to remove 50/60Hz from an ECG (MATLAB/OCTAVE)
 
06:32
http://biosignals.berndporr.me.uk Here I show how to remove 50/60Hz mains interference from an ECG signal using MATLAB/OCTAVE. First, I create the filter-coefficients with the "fir1" command and then I filter the raw ECG with the "filter" command. The fir1 command is a one stop shop for generating the standard filter responses such as low-, highpass and bandpass and bandstop. Check out its help page. The filter command implements both FIR and IIR filters. Here, we just use its FIR part so that the feedback is just set to 1. Note that in MATLAB you will need to install the signal processing toolbox and under OCTAVE you will need to load it with "pkg load signal".

Approximation using chebyshev (PART I)||CALCULATION OF ORDER OF CHEBYSHEV I FILTER
 
16:49
The form for the magnitude squared of the frequency-response function for the Chebyshev filter is |T(jω)|^2=1/(1+(ϵ^2*Cn(ω))^2) where Cn(ω) is an Nth-order Chebyshev polynomial and ϵ is a parameter that controls the ripple size called ripple factor. The passband exhibits equiripple behavior, with the ripple determined by the ripple factor . In the passband, the Chebyshev polynomial alternates between -1 and 1 so the filter gain alternate between maxima at G = 1 and minima at G=sqrt(1/(1+ϵ^2)) my other videos are 1 Controling RGB LED Color and Intensity Connected to ARDUINO using Slider in MATLAB GUI https://www.youtube.com/watch?v=Q87C6FRZAFI 2 Dc Motor Speed and Direction Control Using MATLAB GUI and ARDUINO https://www.youtube.com/watch?v=7KZplmgCwV4 3 How to control devices using MATLAB GUI and ARDUINO https://www.youtube.com/watch?v=OL6CKkSqDnM 4 Interfacing and Displaying Sensor Value on LCD using Arduino https://www.youtube.com/watch?v=9MTgKIWqMlw 5 Tiny dancer Fun. https://www.youtube.com/watch?v=mral00xc7gc 6 How to make a Disco Light https://www.youtube.com/watch?v=lhLGKRm_Aso 7.

Butterworth filter
 
13:26
The Butterworth filter is a type of signal processing filter designed to have as flat a frequency response as possible in the passband. It is also referred to as a maximally flat magnitude filter. It was first described in 1930 by the British engineer and physicist Stephen Butterworth in his paper entitled "On the Theory of Filter Amplifiers". This video is targeted to blind users.

In Depth - Base Theory, Design & Examples of Digital Filtering - FIR Filters for Audio (and beyond)
 
02:36:30
A comprehensive (2+ hour!) yet accessible in scope look at Digital Filtering. Introduction to digital filtering as a prelude to DAC architecture (in the next video) - topics discussed include the basic theory of a digital filter, especially an FIR Filter. Benefits of digital filtering are discussed, followed by a look at the duality between the time and frequency domains (basic explanation of Discrete Fourier Transform), low-pass filtering for FIR filter construction, linear time invariant (LTI) systems, the theory of how impulse response fully characterizes such a system, followed by FIR design (general N-tap structure) and implications, interpolation and its effect on the filter response with Nyquist parameters, and the interpolation filter design. Basic hand derivation from delta-summed unit impulses to our discrete FIR filter equation to showcase the importance of LTI impulse-characterization (while keeping it accessible and the math reasonable) with examples along the way. The general FIR coefficient calculation is explained from the impulse response theory as well. Computational efficiency is briefly discussed. Windowed-sinc method of FIR design heavily discussed: general overview of the method followed by a brief window function overview and a more in-depth look at the Kaiser window for our example. The theory is put to work with two interpolation (4x and 8x from 44.1 kHz fundamental) low-pass filters based on the Kaiser window with an emphasis on the audio band (passband DC-20kHz). Overview of the filter, its characterization as well as measurements with detailed graphs of magnitude response, quantized impulse response, phase shift, phase delay, group delay (& its derivation from phase delay), passband ripple, etc. Finally, we take a look at the filter output with Gaussian white noise applied on the spectrum analyzer to verify performance in a real scenario. The goal is to have a basic understanding of digital filtering as a prelude to DAC architecture (next video), as filtering is key to modern DAC's and makes up a significant portion of the design of a full DAC.

Mobile: (0) 9952649690, Email: [email protected], web: http://www.jpinfotech.org Reconfigurable filters based on the spectral parameter approximation (SPA) technique and its combination with other techniques provide a continuous control over the cutoff frequency (fc). However, when very wide fc range and narrow transition bandwidth is desired, these filters either fail to satisfy some of the specifications or have extremely high complexity. In this brief, we propose an interpolated SPA (ISPA) filter that overcomes all the limitations of all the existing SPA technique based filters, and achieves very wide fc range (equal to approximately the entire Nyquist band) and narrow transition bandwidth along with small passband ripple and high stopband attenuation. Comparison with the state-of-the-art reconfigurable filters is provided via a design example, which shows that the ISPA filter achieves more than 50% savings in the number of multipliers compared to the filter based on the combination of SPA and modified coefficient decimation techniques. The field-programmable gate array implementation results show that the ISPA filter has much lesser group delay and much higher operating speed, but incurs moderate penalty in terms of area compared to the filter based on the combination of frequency transformation and interpolation techniques.

Shaping Equiripple FIR Filter Sidelobes
 
06:45
It is easy to shape the sidelobe structure of an equiripple FIR digital filter designed with the Remez algorithm in MATLAB. Here the 1/f shaping that is advocated in the "Multirate Signal Processing for Communication Systems" text (by Professor fred harris) is performed using the Sketch-a-Filt tool. What is the REASON for doing this type of shaping? As harris explains at length (pages 60-64), lowering sidelobes reduces susceptibility to sidelobe incursion once coefficients are quantized. Moreover, 1/f-style shaping is especially beneficial because outlier impulse response impulses are eliminated and the consequent lowering of the integrated sidelobe level decreases pile-up of aliased energy whenever filter output is re-sampled. The design specimen reproduced here can be seen in Figure 3.23 on page 66 of the harris book. It is shown that linear, square and even cubic sidelobe weighting can be done with just a few button clicks. Wholesale dB level shifting can be readily effected under slider control. While all this is happening, passband ripple is being monitored, and (as harris indicates) the in-band gain disturbance is found to often be only minor.

FIR filter design by windowing: The Kaiser window
 
20:54
The Kaiser window approach allows the control of the ripples of the amplitude response and offers a complete design approach starting from the max permitted ripples and the transition width and then recommends the number of taps and crafts a bespoke window function for the ideal frequency response.
