Dynamically Determining Equiripple FIR Digital Filter Quality Metrics
 
04:00
Slifer is available at http://www.dspcreations.com/slifer1.html Here the quality of an equiripple FIR digital filter is measured. Ripple and transition metrics are determined dynamically, changing as filter coefficients are adjusted. The usefulness of being able to painlessly archive design results becomes clear. This can ease subsequent quantification and comparisons of procedural effectiveness.

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.

Unleashing Ripple to Reduce Digital Filter Gain Transition Width
 
08:57
Sketch-a-Filt is available at http://www.dspcreations.com/sketch1.html A minimum-phase lowpass FIR filter with very low passband and stopband ripples is first presented. Then it is shown that the transition width for the gain can be substantially reduced by liberating the ripple constraints in one or both bands.

we were able to implement a lowpass FIR equiripple filter on FPGA. We've used spartan 3e. We calculated the filter coefficient form matlab and implemented it on FPGA using VHDL.

Filter Stopband Comparision
 
00:44
Comparison of stop band performance of stock and custom high attenuation filters for the Soekris DAM1021. Filters coefficients were applied to a short music sample using SoX to illustrate the behaviour of the stop band. Static filter response plots don't capture the way the stop band behaves whilst filtering audio.
