OVERLAP ADD and OVERLAP SAVE methods

 Overlap-Add and Overlap-Save method is used to perform linear convolution and circular convolution of long data sequences respectively. They are called as block processing techniques as the input signal is divided into blocks and then analysed.  The output signal is the combination of the convolved input signals by removing first few values. The code is then executed by entering the input values and thus checking the result.

  2. This method is useful when the input sequence is very long

  3. These are useful for processing long streams of input

  4. computetionally both methods are equally useful
