Overlap Add and Overlap Save Method are two methods which are helpful for finding discrete convolution of a very long input signal.
In Overlap Add Method, we use linear convolution and in Overlap Save Method we use circular convolution. F.F.T algorithm is used for computing the convolution.
Overlap Add and Overlap Save Method are known as block processing techniques because the input sequence is divided into different blocks and each block is processed separately.
These methods are suitable for processing of real time.

Good explanation
ReplyDeleteOAM and OSM are useful methods for processing real time signals
ReplyDeleteNicely written
ReplyDeleteWe can process long input streams with these techniques
ReplyDeleteOAM can be used in FIR filter for processing
ReplyDeleteOsm discards values and so does not require memory
ReplyDeleteCannot be used for IIR filter design
ReplyDeleteOAM and OSM are not useful for IIR filter
ReplyDeleteOAM and OSM are not useful for IIR filter
ReplyDeleteAliasing effect can be observed in OSM whereas this effect is absent in OAM
