Hello there,(adsbygoogle = window.adsbygoogle || []).push({});

if I have a impulse train as f(t) with a frequency of 100 khz, and cos(w_0*t) = g(t) with frequency of 10 khz, how do I go about determining the signal spectra, (i.e. harmonics n = 1,2,3...)? I determined the fourier transform, but I get stuck as to what to do with it.

Thanks.
