Dmitrij said:No doubt, convolution and multiplication are different concerning their nature and physical and mathematical senses. All the distinguishing differences are underlined in the previous replies.
Still one coincedence exists. If you evaluate the linear (don't confuse it with circular convolution, which arises in DFT computing process) convolution of 2 discrete-time sequences you'll find out that the final result is the same as if you have multiplied 2 polynomials with coefficients, equal to sequences' samples. But it's the coincedence, nothing more. The sense of these 2 operations is quite different.
With respect,
Dmitrij

ya i make mistake..in wrting the complete sentence..i appreciate for ur correction...
i mean the same ,what u have judge.."the dirac impulse", in continuse time...have its Amplitude , touches to infinity...am i correct or not ???
Q: my question is , i have the train of continous( dirac) impulses, and i want to convove it with x(t) and x?
i which case it is possible to plot in MAtlab ,with x or x(t)??????????
regards
