Question about single tone signals

  1. Apr 9, 2010 #1
    what is the bandwidth of single tone signals?

    taking the F.T. for a cosine signal gives a delta at the signal's frequency, so does it mean that its bandwidth is zero since it is occupying only a single freq. in the FD.

    You get deltas at both the positive and negative frequencies, right? And yes, I believe it would be correct to say that an infinite tone has zero BW.
