EXP 4B. OVERLAP SAVE METHOD

In this experiment ,we have implemented function to implement Fast Overlap Save Algorithm to perform filtering of long data input sequence.

Overlap Save method is one of the Linear filtering method

Here we decompose the long sequence input signal x[n] with appropriate L using N=L+M-1 formula.Also we modify the input signal after decomposing it.

In the output signal first M-1 points are corrupted by aliasing and they are discarded.
