freqresponse [phonTools]


This function plots (and optionally returns) the frequency response for the digital filter whose transfer function is determined by the numerator and denominator filter coefficients given in b and a.

 

Code used to generate examples:


library (phonTools) ## generate a segment of the sinc function filt = sinc (seq (-5,5,.3), normalized = TRUE) par (mfrow = c(2,1), mar = c(4.1,4.1,1.1,1.1)) plot (filt, type = 'b') ## treat it as a low-pass FIR filter and inspect its frequency response freqresponse (filt, 1)
