WebBandpass FIR Design with a Low Group Delay. An interesting application of arbitrary magnitude and phase designs is the design of asymmetric FIR filters that sacrifice linear phase in favor of a shorter group delay. Such filters can still be designed to maintain a good approximation of a linear phase on the passband. WebThe Idea of “More Flat Phase” Design.
