Webphase linearity. For this reason, it is not preferable to use IIR filters in digital signal processing when the phase is of the essence. Otherwise, when the linear phase characteristic is not important, the use of IIR filters is an excellent solution. An elliptic filter is a signal processing filter with WebFor 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 ). If the phase response is nonlinear, then the relative phases of the sinusoidal signal components are generally altered by the filter.
