On the Design of Complex Coefficient Multifunction Filters
ABSTRACT This work presents novel designs of multifunction topologies for simultaneously extracting the real and imaginary components of complex band‐pass and notch filters, which are derived from prototype first‐order low‐pass and high‐pass filters. The real and imaginary parts of the complex filters are then post‐processed to compute the instantaneous magnitude. The performance of both the multifunction topologies and post‐processing stages is evaluated using the OrCAD PSpice suite, as well as through experimental results.
