A general analysis of the effect of the power-law envelope detector by the use of output harmonic components on signal-to-noise ratio (SNR) is performed. By using multiplication and filtering, the additional zero-frequency components are obtained from output harmonic components of the power-law envelope detector. An general expression of the improvement factor on SNR is obtained which is applicable to non-Gaussian noise. It is found that the output SNR can be improved by using the additional zero-frequency components from the output harmonic components of the power-law envelope detector.
