The use of synthetic signals in the study of nonlinear phenomena in a medium

The method of frequency synthesis of signals is considered in relation to i ts possible application to the study of nonlinear effects in waves, caused by the medium in which they propagate. It is shown that if the initial spec tra of synthesized and nonsynthesized signals are identical, comparison of their spectra after their propagation in a medium allows the identification of nonlinear effects after the synthesis of narrow-band processes. Consecu tive stacking of waves radiated with different polarities is promising for the study of nonlinear effects in broad-band processes.
