MT-002: What the Nyquist Criterion Means to Your Sampled ...

MT-002. The Nyquist bandwidth is defined to be the frequency spectrum from dc to fs/2.The frequency spectrum is divided into an infinite number of Nyquist zones, each having a width equal to 0.5fs as shown. In practice, the ideal sampler is replaced by an ADC followed by an FFT processor.
