EXP 4 - Overlap Add Method and Overlap Save Method

Overlap Add and Overlap Save Methods are used to process real time signals. Both OAM and OSM breakdown the signal into segments , process each segment and then combine the segments into one final output signal. OAM and OSM methods use FFT because high computational speed is required.

In the experiment OAM and OSM were applied on a 13 point sequence. Because of their speed OAM and OSM are preferred for real time processing.

  1. It is said that OAM and OSM are suitable for real time processing..can you give some insight on that?

  2. Yes because OAM and OSM are block processing techniques. They are preferred over FFT because FFT requires parallel input and real signal is sequential.

  3. In OSM, aliasing effect is present but is absent for OAM.

  4. Also OAM and OSM are useful methods for processing real time signals

    1. Yes! They are preferred over FFT as FFT cannot process real time signal.

EXP 6 - Chebyshev Filter design

After designing Butterworth filtwr there was another IIR filter that was to be designed and that was Chebyshev Filter. The filter was designed by coding in SCILAB.  Both Low Pass and High Pass Chebyshev filters were designed and the results were verified by manual calculations. Increasing  the sampling frequency increased the  accuracy of the results obtained.

EXP 5 - Butterworth Filter Design

After learning DFT and FFT techniques it was finally time  to start designing filters. We started with IIr filter  design. The first filter that we were going to design was a Butterworth Filter. Butterworth filter  was designed by using SCILAB. The results were verified by running the program and manually solving  using the same set of values. Results for both Low Pass and High Pass Butterworth filter were verified.

EXP 2 - Discrete Fourier Transform

Discrete Fourier Transform is used to transform signal in time domain to frequemcy domain. In this experiment, we ran a C program to find the DFT of a 4 -ponit and an 8-point sequemce. Also, we plotted their magnitude spectrum. From the magnitude spectrum it was observed that expansion of input signal in time domain gives compressed spectrum in frequency domain.
