Back to c programming for this experiment, we performed overlap add and overlap save methods to determine linear convolution. This method is the one that is of more practical use as it allows a very long continuous signal to be processed.
We use the overlap add method to compute the convolution of a signal of a long length.Which is broken down into small sequences and after performing the operations on each of them,they are combined to obtain the final output.Breaking down i.e. buffering small portions of the signal allows better computational efficiency.These are algorithms for decreasing delay in getting the output.
This experiment actually had to be done before the two filter designs but we missed this due to some negligence that cost us our grade.One of the lowest grades i have ever got in my journal uptil now was a little bit disheartening.

i think u can also add why oam/osm is used
ReplyDeleteOverlap add method and overlap save method are used for filtering long data sequence. These methods are used in practical world for multipying two signals.
ReplyDeletein OSM input is divided into parts whereas in OSM N-1 zeros are added at the end of signal at input signal
