hello friends....i m studying sgnal n system ....plz tell me what r half wave symmetric waves....

 

Refer to the discussion on half wave symmetry at the following link ...

http://en.wikibooks.org/wiki/Signals_and_Systems/Periodic_Signals

 

thanks buddy for this....but i have already seen this....this is insufficient....plz tell me any material with some examples on this topic....

 

Can you tell us how that material is insufficient? What information do you need in addition?

 

In techniques such as the Fourier analysis of signals, waveform symmetry features may be used to simplify the calculation of the Fourier coefficients.

Is this what you are enquiring about?
