HI Sir,

You are giving good example, but for me it will be better if you have a small images showing this property in real world, it will be far better....


Thanks very much..!!

Here's a drawing of a sine wave (red) and a delayed sine wave (blue). Note the blue one is zero for 0.25 seconds because the delay factor for that wave is 0.25.

I think this is in time domain, if we considered i\t freq. or e^-jwt how it will be shown??

Thanks.

Hello,

Not sure what you are asking. The table came from a book, "Engineering Circuit Analysis".

Its simple as in time domain, the signal is shifted in t sec. ,but-in freq. shifted upward only ,why ??

The Fourier transform of the delta function is the unit step. There is no "shifting upward" going on.

That's because the amplitude of e^-jwt0 is 1 regardless of what w is.

OK, sir tell the diff. in Freq. & time convolution..........

Convolution in the time domain is just multiplication in the frequency domain. If you don't make any effort next time I won't answer any more.
