EXP 1 - Convolution and Correlation

In the previous semester we had studied convolution and correlation. In this semester we applied the codes for convolution and correlation and verified the results with theoretical reaults. Linear convolution, Circular Convolution and Linear Convolution using Circular Convolution were calculated. It was observed that Circular Convolurion gives aliased output.

Correlation is used to find the degree of similarity between two signals. We calculated autocorrelation and cross correlation.

      Length of the convolved signal is N>= L+M-1

    Auto correlation results give energy of the signal at 0th value

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.
