What are poles & zero in Real.......??

[MrAl]

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.

 

[MrAl]

Hi again,


Is this what you wanted to see?

 

[koolguy]

From where you got this,that mean in freq. domain the freq. rise by to??

 

[MrAl]

Hello,

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

 

[koolguy]

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

 

[MrAl]

What do you mean shifted upward?

 

[koolguy]

Hello Sir,

I have shown in this image.....

 

[birdman0_o]

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

 

[MrAl]

Hello Sir,

I have shown in this image.....

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

 

[koolguy]

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

 

[birdman0_o]

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.

 

[koolguy]

A special thanks To MR AL. for the help & other member my exam of it is over so, no more discussion on it..............


The End.....................!!

 

[MrAl]

Hello again,


I hope you did well on it

I hope you did well on it

It was fine not so well, because my course was not completed..
