Butterworth filter group delay

WebThe group delay response of a filter is a measure of the average delay of the filter as a function of frequency. It is the negative first derivative of the phase response of the filter. If the frequency response of a filter is H(ejω), then the group delay is. τ g ( ω) = − d θ ( ω) d ω, where θ(ω) is the phase, or argument, of H(ejω).
