EXPERIMENT-5 OAM and OSM

This experiment was to perform Linear filtering using OAM (Overlap Add Method) and  OSM (Overlap Save Method). Here we have a long sequence data x[n] whose response has to an impulse function here(h[n]) has to be observed. For this the length of the data sequence must be sufficiently larger than the impulse that is applied to the system.  In OAM we decompose the long input data sequence into smaller segments of lesser length, then we operate linear convolution to get segmented outputs of all the decomposed segments. After that we combine these outputs to obtain the final output. In OSM also we decompose the input data into smaller segments.The answer which we get for the linear convolution of the input data is the same by OAM method and OSM method.
