Abstract :
A sinusoidal signal and Gaussian noise lying in a narrow bandpass through an ideal limiter with a hysteresis, followed by a filter that confines the output to the vicinity of the input frequencies. It is indicated by experiments that a significant improvement in the output SNR at low input SNR can be achieved by this nonlinear device.
