What is the Nyquist rate?
The Nyquist rate or frequency is the minimum rate at which a finite bandwidth signal needs to be sampled to retain all of the information. For a bandwidth of span B, the Nyquist frequency is just 2 B. If a time series is sampled at regular time intervals dt, then the Nyquist rate is just 1/(2 dt ).What is the formula of Nyquist rate in PCM?
According to the Nyquist sampling theorem, the minimum allowed sampling rate would be 2B Hz, hence there will be 2B samples per second each quantized to M levels, yielding a total of D=2B log2(M) bits per second data rate to represent the analog message signal.- From earlier parts, we know that sinc2(200t) has the higher bandwidth equal to 200 Hz. Correspondingly, the Nyquist rate is 400 Hz and the Nyquist interval is 1/400 seconds.
