Hello. Thought I could add something on negative frequency. Since Sinusoids (Cosine and Sine) are projections of rotational motions of complex exponentials , Negative frequency can be interpreted as a rotational motion in anti-clock wise direction .

@SHOAIB REHMAN SOOMRO: If the information on +ve and -ve frequency are different, we need to send the whole chunk of spectrum. If you recall, there were single side band techniques where one half of the spectra was shaved off (as the information in the -ve half was redundant)

Is there any effect of -ve frequecy on Bandwidh ?
if yes then why ?
if no then why ?

@vivek: The power of the spectrum at +ve and -ve need not necessarily be the same
