WebDec 4, 2024 · Look at the AC response for a low pass filter and the pole (for an ideal filter, real filters already decrease -3db). The pole w 0 is where the transfer function starts to decrease. You can stack more than one pole at one location. Each pole gets the transfer function. 1 1 + s / w 0. WebAug 13, 2024 · I have the output of a fir2 function, that is a digital fir filter. I can evaluate it for a given frequency range using freqz, but I need to evaluate it even for the complex variable "s". Therefore, my idea was to transform the fir filter into a continuous transfer function (TF) and, then, evaluate TF for a given complex number using evalfr.
