Linear Filtering using OSM and OAM

Linear Finite Impulse Response is implemented using any of the two algorithms of OSM and OAM. Overlap Add & Overlap Save Methods are particularly used to perform convolution on longer input of data sequences by breaking actual input signal into smaller length of different signals and then performing convolution on individual data streams. .In OAM method, the values which get overlap were added together. In OSM method, the values which get overlap were discarded.In OAM, the individual output signals are added as it is, while in OSM, the individual output signals have their first “N-L” terms removed and then remaining terms be subtended one after another.
