Hey there !

The Nyquist frequency, named after electronic engineer Harry Nyquist, is half of the sampling rate of a discrete signal processing system. It is sometimes known as the folding frequency of a sampling system. ... The Nyquist rate is twice the maximum component frequency of the function being sampled.

Hope it helps you !

Sampling frequency greater than the Nyquist rate is called oversampling.

Explanation:

  • In oversampling, We sample the signal at a frequency more than the Nyquist rate. Nyquist rate is basically a rate whose bandwidth is double than a band limited function or the band limited channel.
  • Nyquist rate has been introduced by Harry Nyquist. Oversampling improves the overall resolution and decrease the noise. Oversampling has a good anti-aliasing filter performance due to which it can reduce the aliasing.
