'A basic modulator circuit is shown in Figure Q8). Modulation is multiplication between data signal. m(t) and a carrier signal. c(t) The process yields a new signal, v(t)
Q8
Analyze the Fourier Transform of the signal v(t) by using modulation properties.
Sketch the spectrum of signal v(t).
m(t) = 1
v(t)
c(t) = cOS Wct
