Linear convolution was performed first by using OAM method and then OSM Method. There were 4 decomposed signals and N=8. OAM and OSM are efficient ways of calculating very long signal x[n] and a finite impulse response h[n].

ReplyDeleteoverlap add method is used for long input sequences as the entire input sequence cannot be processed at the same time.
ReplyDeleteWhich one do you think is the most efficient in the above methods?
ReplyDeleteOSM
DeleteBoth the algorithms are equally efficient. There is no question of which one is better.
DeleteOAM and OSM are efficient ways to calculate convolution between very long signal x[n] and finite impulse response h[n].
ReplyDeleteOAM and OSM methods are used wherever the whole input signal has not been given but computations of the already stored signals are to be done.
ReplyDeleteOAM and OSM methods are useful for real time applications.
