Development of the automated measurement system for identification of multidimensional transfer functions of nonlinear devices at multitone test signals

Abstract

Offers the modified block diagram of multidimensional transfer functions (MTF) meter in which one considerable magnification of an exactitude of measurements of MTF can be obtained as a result of minimization of a peak-factor of a multitone measuring signal. The wideband ideal /spl pi//2-phasor of heterodyne channel is changed by a simple nondispersing delay line with arbitrary phase shift.
