Linear Filtering techniques of Overlap Add Method (OAM) and Overlap Save Method (OSM) were used on DSP Board.
They both allows us to calculate the convolution of very long sequences. Overlap add involves adding seeveral values in the output to recover the final signal, whereas overlap save does not require any addition in this step. This might be important if you want to consider the numerical precision of your output, or if you want to reduce the number of addition operations.

Was the output same in both cases?
ReplyDeleteWhich is better OAM or OSM?
