Abstract :
The output signal-to-noise ratio (SNR) of a frequency doubler is calculated using the transform method for nonlinear systems with stochastic inputs. The class of nonlinearities considered is the even 
th-power-law devices. It is found that the squarer ( 
) is optimum at low SNR, while for high SNR, 
is best. Choice of the bandpass filters in the system is also considered.
