Envelope and Angle Response of Asymmetrical Narrow-Band Networks

This paper outlines a general approach to the evaluation of envelope and angle response of narrow-band networks including asymmetrical networks. From a known constellation of poles and zeros of a network in the -plane, approximate linearized transfer functions are developed which relate envelope and angle response of the network to the amplitude modulation of the forcing function for small signal conditions (shallow modulation). The transfer functions are expressed in terms of two auxiliary constellations in the -plane, where is equivalent to the complex frequency of modulation.
