摘要
Spectral component discrimination and the estimation of one or more signal frequencies are classical problems in signal processing. The purpose here is to study a new technique intended to increase the frequency resolution, called frequency-filtering zoom (FFZ). The advantage of the method is that it gives a faithful reproduction of the amplitude and phase spectra of signals, in contrast to existing methods which need a phase correction. Moreover, our zoom has been designed to enable software real-time analysis of low-frequency signals.
