What Is Zero Padding?what Are Its Uses?

Answer»

Let the sequence x(n) has a length L. If we WANT to find the N-point DFT(N>L) of the sequence x(n), we have to add (N-L) zeros to the sequence x(n). This is known as ZERO padding.

The uses of zero padding are:

  1. We can get better display of the FREQUENCY SPECTRUM.
  2. With zero padding the DFT can be used in linear filtering.
