Can someone please tell me the physical significances of transforms and the relations between them!!
Regards,

Hey!
Transforms are just a different way to look at the problem at hand. They facilitate analysis of signals...
You can say that Fourier Transform is the representation of a signal as a combination of sinusoids or complex exponentials...

Added after 3 minutes:
And also,
Fourier Transform is a special case of Laplace Transform. In LAplace transform, the constituents are exponential sinusoids....
Z-transform is a counterpart of Laplace transform in the discrete domain.
Ciao,
asymbian.

| Transforms are used for moving/transforming a signal from one domain to another. For instance the Fourier Transform is used to transfrom a signal from the time domain to the frequency domain and vice versa. The Z Transform is used to transform a signal from time domain to the complex plane.

Hi again..
Please refer "The Scientist's And Engineer's Guide to DSP". It has a very good explanation of concepts and in a very general, non mathematical language.
