WebAn integer times the sampling rate differs from the actual signal frequency by the observed, aliased frequency. We'll put the integer in green to make it obvious. 1000 - 5 *202 = 1000 - 1010 = -10 Hz (period = 0.1 s, as seen in the above figure). 0.9 Hz - 1 *1 Hz = - 0.1 Hz (several previous examples). 1000 - 909 *1.1 = 0.1 Hz. WebSampling at the Nyquist rate of fS = 2*fIN is a classic problem. As an example, consider N = 4096, fIN = fS/2, M=N/2. Equation 5 evaluates as ((h1 h2)/4096) = INT. If we substitute h = …
