WebThe Nyquist sampling theory dictates that a signal that is sampled with a dwell time DW can only accurately represent signals up to a maximum frequency ± f N, where f N = 1/(2 × DW). In the absence of filtering, frequencies outside this Nyquist threshold will fold back into the spectrum such that a signal of frequency f N + δ f will be represented in the spectrum at … WebFind many great new & used options and get the best deals for Theory of Discreet and Continuous Fourier Analysis, Isbn 0471628727 at the best online prices at eBay!
