WebOct 14, 2005 · The delay through a linear phase FIR filter is half the filter length. Since a CIC filter is also a linear phase, the delay through the CIC will be half the length of its … WebThe group delay is a convenient measure of the linearity of the phase with respect to frequency in a modulation system. Basic modulation system. A device's group delay can be exactly calculated from the device's phase response, but not the other way around.. The simplest use case for group delay is illustrated in Figure 1 which shows a conceptual …

WebFilters that do not operate in real time (e.g. for image processing) can be non-causal. This e.g. allows the design of zero delay recursive filters, where the group delay of a causal filter is canceled by its Hermitian non-causal filter. Stability. A stable filter assures that every limited input signal produces a limited filter response. A ... WebAn important issue in many applications is the delay associated with the processing of a signal. A common measure of delay is the group delay defined as t=−df/dv.
