Experiment 4: Filtering of Long Data Sequence

We performed Filtering of Long Data Sequence using Overlap Add Method(OAM) and Overlap Save Method(OSM) using C programming. These methods find their applications in processing real time signals. These algorithms decrease the delay in getting the output. In OAM the signal is decomposed into N sequences and zero padding is added. In OSM the decomposed signal of the first short length consists of zero, since the second signal consists the first signal as well, it saves the data.

  1. OAM 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.

  2. Yes and they are used for real time processing.
