Resumo
In this paper, we numerically studied the interaction of signal and noise in a second-order nonlinear active filter. The filtering of the signal against a background of intense noise through a nonlinear filter with a bandpass filter at output is analyzed. The output signal-to-noise ratio is established as more than three times higher than the similar ratio without using a nonlinear filter.
