Convolution and Correlation
To perform and verify the results of the theoretical concepts
in Digital Signal Processing, it is very important to have a good command over
a programming language like C.
Through the first experiment, output of Convolution (
Linear, Circular and Linear Convolution using circular) and Correlation (Auto
and Cross) codes were verified with the results of mathematical method.
Convolution is a method of combining two signals and gives an
output signal. So two signals of different length were taken for Linear and
Circular convolution and aliasing effect was observed in case of Circular
convolution. Application of Convolution is to find the output of the system.
Correlation is a measure of degree of similarity between two
signals. We found the Auto-Correlation and Cross Correlation of original, delayed and scaled signal.
What is the significance of the value at y(0) in autocorrelation?
ReplyDeleteThe value at y(0) in aftercorrelation gives the Energy of the signal.
DeleteIs auto correlation of delayed signal same as that of original signal?
ReplyDeleteYes. Autocorrelation of delayed signal is same as that of autocorrelation of the original signal.
DeleteOk thank you 😄
DeleteWell explained
