EXPERIMENT 4: Filtering of
long Data Sequence
Day four of DSPP practicals. Take the name of the devil and the devil appears. We talked about challenges in the previous practical session and here was one in the form of this experiment.
This particular experiment took some research and studying some theory. It also took the collective efforts of our entire batch.
The aim of this experiment was to perform filtering of Long Data Sequence using Overlap Add Method and Overlap Save Method.

The aim of this experiment was to perform filtering of Long Data Sequence using Overlap Add Method and Overlap Save Method.
We implemented the filtering of Long Input Sequence using
Overlap Add / Overlap Save Algorithm.
The Input Specifications were given as length of long data
sequence and signal values and length of impulse response M and Signal values.
We concluded that Overlap Add Method(OAM) and Overlap Save
Method(OSM) are efficient methods to calculate the convolution between long
length signal and finite impulse signal.
It was one of the longest practical sessions in this semester but we finally got our rewards. Wiping the proverbial sweat from our foreheads, we exited the lab.

Well written!
ReplyDeleteIt is used for real time processing in FIR filter
ReplyDeleteOSM and OAM are used for long signals.
ReplyDeleteAlso,In this method the signal is equally divided in short length signals and then convolution of these short length signals are obtained.
ReplyDeleteThe overlapped portion is discarded in OSM whereas it is added in OAM to get the required output sequence.
