signal correlation help

[aruna1]

i have three questions

1. what is meant by the correlation of two signals?
2. what is meant by correlation coefficient
3. state parsvals theorem

can some one help me to find answers?

 

[Hayato]

Have you studied Fourier/Laplace Transform?
Parseval theorem tells you the relation between the squared norm of the time-function and the squared norm of the frequency-function. Remember that?

 

[aruna1]

well i have learned fourier and laplace but havent correlation.so can you please explain more simple manner
thanks

Why is google or Wikipedia insufficient for your purposes?

 

[aruna1]

well its littel difficult to me to understand.some simpler version would be nice

I went to read the following:
Cross-correlation - Wikipedia, the free encyclopedia
and
Correlation - Wikipedia, the free encyclopedia
and
Parseval's theorem - Wikipedia, the free encyclopedia

Now either you have the Mathematical stones to understand the articles or you don't. How far did you get exactly?

Parseval Theorem is one of the basis of Fourier transform for circuitry analysis. If you studied well, you should know.
