OVERLAP ADD METHOD AND OVERLAP SAVE METHOD

OSM (Overlap Save Method) and OAM(Overlap Add Method) are linear filtering method. In this practical, we have performed OSM and OAM using 13 point input sequence x(n) and 4 point h(n). The obtained output of OSM and OAM method is same for given input sequence.In OAM, the input signal was decomposed into non overlapping blocks and their corresponding y(n) was calculated using linear convolution and then these signals are combined to obtain the final output.
In OSM, the input is decomposed into overlapping blocks and their corresponding y(n) is calculated through circular convolution and then these signals are concatenated to give the final output.
