The aim of this experiment was to perform filtering of Long Data Sequence using Overlap Add Method and Overlap Save Method.We implemented the filtering of Long Input Sequence using Overlap Add / Overlap Save Algorithm.The Input Specifications were given as length of long data sequence and signal values and length of impulse response M and Signal values.
We concluded that Overlap Add Method (OAM) and Overlap Save Method(OSM) are efficient methods to calculate the convolution between long length signal and finite impulse signal. Both the OAM and OSM require same amount of computations and hence memory.

ReplyDeleteYou have mentioned both of them require same memory. In OSM since we do not save the values of output signals of each block which we do in case of OAM shouldn't OSM be consuming less memory ?
