EXP 4: FILTERING OF LONG DATA SEQUENCE

We performed Filtering of Long Data Sequence using Overlap Add Method(OAM) and Overlap Save Method(OSM).. The 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. OAM and OSM are used in processing real time causal signals

    Osm is slightly efficient as it doesn't
    Include effect of overlapping transients

    In signal processing overlap add method is an efficient way to find discrete convolution of long data signal using fir filter

    When the length of the signal is very long because of very high sampling rates, waiting for the entire signal to arrive and then processing the signal may cause very large delays in processing. The large signal is to be stored and this may increase the cost and performance of the system.
