Analytical expressions are obtained for predicting the amplitudes of the harmonics and intermodulation products at the output of an envelope detector excited by a signal formed of a carrier plus a number of sidebands. These expressions are in terms of the ordinary Bessel functions with arguments dependent on the modulations indecies. Comparison between results obtained using the proposed technique and previously published results is performed to establish the accuracy of the proposed technique.
