Overlap add and Overlap save method

The aim of the experiment was to filter long data sequence using OSM and OAM. The inputs are very large in these methods. They are used for decreasing the output delay. Also, aliasing effect is present in OSM in the initial M-1 samples in the corresponding output block. This effect is absent in OAM.

  1. They decrease the delay as the entire input sequence need not be known at the start of convolution. It also uses FFT which increases the speed.
