overlap add and save method

We used linear convolution method  for overlap add method.Overlap Add method is based on decomposing of signal into the sequence and process each sequence with DFT algorithm method.Then we combine each sequence to get final output sequence.
In overlap save method we used circular convolution method.Here we discard repeated sequence  and get final output sequence.
OAM OSM methods are used to find output of FIR filter for real time input signals.
