WebGroup Delay A more commonly encountered representation of filter phase response is called the group delay, defined by For linear phase responses, i.e., for some constant , the group delay and the phase delay are identical, and each may be interpreted as time delay (equal to samples when ). WebThe group delay of a filter is a measure of the average time delay of the filter as a function of frequency. The group delay is defined as the negative first derivative of the filter's phase response. If the complex frequency response of a filter is H ( e j ω), then the group delay is τ g ( ω) = - d θ ( ω) d ω,

WebDec 16, 2013 · Group delay is basically how much a frequency passing through the filter will be delayed, and it's a function of frequency (IIR filters have non-linear group delay). You can calculate the maximum group delay of your filter, or you can just eyeball it so that you process the entire signal. If you have Matlab, try using the grpdelay function.
