Calculating stopband cut-off frequency and stopband attenuation for FIR lowpass window filter

Some helpful advice: The order of 5 for an FIR filter is very small. I assume from the OP's comment that the exercise will be to compare FIR and IIR filters for very small order. Plotting the spectrum ...

Phase response of non-symmetric FIR filters

The phase is indeed not linear as we would get when the impulse response is symmetrical or anti-symmetrical about its center coefficient. In the plot of magnitude and phase (which we can get using the ...

How can I make use of Saramäki and MATLAB implementation of the Remez multiple exchange algorithm for FIR filter design

700 coefficients seems a high number for remez. If I try using Matlab's design tools, it seems get numerical problems between 300 and 350 coefficients.

Generating FIR filter in Web Audio API

I stumbled into FIR filters this week for another reason, and had a go implementing one with ConvolverNode as Marcus suggested. I found a library called fili.js and used the FIR code from there with ...
