Fourier Transform
  1. The modulation property of the Fourier transform. (a) Let f ( t ) be a signal, s 0 a number, and define
g ( t ) = f ( t ) cos ( 2 π s 0 t ) .
Show that
F g ( s ) = 1 2 F f ( s s 0 ) + 1 2 F f ( s + s 0 )
(b) Find the signal (in the time domain) whose Fourier transform is pictured, below.
