PRODUCTION DATA.
Linear phase filters exhibit constant delay time versus input frequency (that is, constant group delay). Linear phase filters have the property that the time delay is constant from any instant of the input signal to the same instant of the output data, and is independent of the signal nature. This filter behavior results in essentially zero phase error when analyzing multitone signals. However, the group delay and settling time of the linear phase filter are somewhat larger than the minimum phase filter, as shown in Figure 41.
