Experiment 4 - Overlap Add Method (OAM) / Overlap Save Method(OSM)

In this experiment we had to implement filtering of long i/p sequence using OAM/OSM  algorithm .
After performing the experiment and observing the results I learnt that OAM and OSM are used for processing long data sequences .

  1. OAM and OSM are efficient ways to calculate convolution between very long signal x[n] and finite impulse response h[n].

  2. OAM and OSM methods are used wherever the whole input signal has not been given but computations of the already stored signals are to be done.

  3. OAM is slower than OSM because less number of steps or computations.
