Filtering of data sequence using OSM & OAM

In the fourth experiment we perform OAM and OSM. Fast convolution can be accomplished by overlap add(OA) or Overlap save(OS) methods.
Two methods are used to evaluate the discrete convolution −

Overlap-save method : If the components are observed, the
values from both convolutions result in the desired “fully engaged” filter during this region in
time. Therefore, overlapping smaller length convolutions and then summing the appropriate
overlapping segments will form the continuous output. This approach is called the “OverlapAdd
Method” for continuous signal processing.

Overlap-add method : Overlap–save is the traditional name for an efficient way to evaluate the discrete convolution
between a very long signal x(n) and a finite impulse response (FIR) filter h(n).
