Abstract :
The SNR of a harmonic signal in additive white noise is computed after transformation by an arbitrary memoryless nonlinearity. With a simple saturating nonlinearity having direct electronic implementation, an amplification of the SNR can be obtained, an outcome which is inaccessible with linear devices.
