Bandpass sampling characteristics and simulation of digital signal processing is first of all necessary for converting an alog signal into a digital signal, the most commonly used method is sampled, the Nyquist criterion requires that the sampling frequency is greater than or equal to twice the highest signal frequency, the higher center frequency band The narrower signal using the Nyquist criterion, will result in high sampling frequency at the same time there are a lot of band gaps
