Overlap add and Overlap save method are the algorithms used to calculate the convolution result when the whole of the input is not available but the output is needed. The only need for such an algorithm would be in real time applications.
I didn't understand how breaking up the input signal into smaller parts would still give the same convoluted answer, as it should need all possible inputs given. But the program gives identical results, so I have to accept it.
Aliasing effect can be observed in OSM whereas this effect is absent in OAM
ReplyDeleteWe did give all the inputs at the start , that was the only way this method worked
ReplyDeleteOAM And OSM is used for finding output of IIR filter for long data sequence.
