Summary/Abstract: The work presented in this paper provides a theoretical analysis and estimation of the most important power parameters of the class B amplifiers operating with random signals and resistive loads, i.e. loudspeaker with impedance compensation. Some parameters of the random signals are exposed and energy relation between the sine-wave signals and the random signals are given via the coefficient of ARV-compliance. Analytical expressions of the power relations are derived for operation with random signals with Gaussian distribution. The simulation results are given that confirm the theoretical statements, as well as data of real-world amplifier measurements with NI USB-6211.
