THE CALCULATION OF FREQUENCY-MODULATION DISTORTION IN LINEAR NETWORKS.

Abstract

A numerical method for calculating the steady-state FM distortion in a linear passive network using a sideband-type of analysis is developed to achieve economy of digital computer time and, for a given network, to find the number of significant sideband pairs associated with a given maximum allowable level of FM distortion. To illustrate the application of the method, the FM distortion introduced by a bandpass filter is calculated over a range of signal parameters. A useful byproduct of the FM distortion calculations is a formula for the minimum ratio of the bandwidth of the filter to twice the frequency deviation of the input signal necessary to assure that the FM distortion introduced by a bandpass filter is less than 5 percent.
