WebReal and Complex Linear-Phase FIR Filters 1 1 Introduction Most analyses of linear-phase FIR ﬁlters assume real coefﬁcients. Here we start with an analysis of the more general case of complex coefﬁcients and later specialize those results to real coefﬁcients. The frequency response of a (generalized) linear-phase system can be expressed as WebWhich one is better? Maybe it's best to compare alternative designs for a particular set of requirements. In general, FIRs have the advantage of linear phase, but IIR allpasses can reportedly achieve "almost" linear phase. The advantage of IIR filters is almost instantaneous response, whereas FIR filters pay for the linear phase with longer ... cto calculations

In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. Consequently, there is no phase distortion due to the time delay of frequencies relative to one another.
