Development of the automated measurement system for identification of multidimensional transfer functions of nonlinear devices at multitone test signals
A.V. Brener, S.V. Trushin · 2003
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.
