A signal m(t) is multiplied by a sinusoidal waveform of frequency fc such that v(t)=m(t) cos 2pfct If Fourier transform of m(t) is M(f), Fourier transform of v(t) will be
Correct Answer: 0.5 M(f + fc) + 0.5 M(f - fc)
Explanation:
It is a modulation process. The resultant has (f + fc) and (f - fc) terms.
