What is Nyquist sampling rate?

Nyquist sampling rate is the rate which samples of the signal must be recorded in order to accurately reconstruct the sampled signal A signal sampled every T0 seconds can be represented as: One way of understanding the importance of the Nyquist sampling rate is observing the fourier spectra of a sampled signal

What is the Nyquist theorem?

Nyquist Theorem The Nyquist theorem states that in order to fully describe objects they must be sampled at twice the smallest resolvable object in the data. For iterative restoration the Nyquist sampling rate is the minimum that is necessary; higher sampling rates will lead to superior deconvolution results.

How to construct a continuous-time signal from Nyquist samples?

Recall that a continuous-time signal g (t) ofbandwidth B Hz can be constructed from its Nyquist samples (which are at a rate of 2B Hz) using the interpolation formula (6.10). We can construct a signal from the given 2 B pieces per second as the values of the Nyquist samples g (kT s ) in Eq. (6.10).
