Nonlinear FM Distortion Equalizer
TLDR
It is shown that, using analog multipliers and differentiators, a baseband equalizer can be designed which eliminates all types of distortion products and an equalizer circuit was designed for 1800 channel microwave FM systems.Abstract:
A new approach to FM distortion equalization is suggested and a nonlinear equalizer operating in the baseband frequency range is presented. It is shown that, using analog multipliers and differentiators, a baseband equalizer can be designed which eliminates all types of distortion products. The synthesis of the FM distortion equalizer is given with minimum number of multipliers. Using the synthesis procedure an equalizer circuit was designed for 1800 channel microwave FM systems. Experimental results obtained with the equalizer are discussed.read more
