Abstract

SummaryAn updated definition of group delay bandwidth in analog filters is introduced in this work. Unlike existing definitions, this new definition considers simultaneously the value of the group delay and filter gain, leading to minimized distortion in the filter output. In addition, it offers the capability of handling wide‐band signals without introducing errors in the shape of their envelopes. Selected first‐ and second‐order filters are studied and simulation results are provided to validate the efficiency of the new definition.
