Abstract
This chapter considers the nonlinear distortions of harmonic signal and Amplitude Modulated (AM) signal on the passage through single-ended and push-pull nonlinear power amplifiers with memory and without it. The amplifier characteristic is preset by the cubic polynomial. We consider two operating modes of amplifier for harmonic signal: cutoff mode and non-cutoff mode. Demodulation of AM signal is performed using a coherent quadrature amplitude detector. The distortion estimate based on Total Harmonic Distortion (THD). Dependence of THD versus cutoff angle for harmonic signal and THD versus amplitude sensitivity m for AM signal are calculated.
