Q2 (a) A basic modulator circuit is shown in Figure Q2(a). Modulation is multiplication between data signal, m(t) and a carrier signal, c(t). The process yields a new signal, v(t). Analyze the Fourier Transform of the signal v(t) by using modulation properties. (i) (ii) Sketch the spectrum of signal v(t). m(t) = 1 v(t) c(t) = cos w.t Figure Q2(a)

signal system 

A basic modulator circuit is shown in Figure Q2(a). Modulation is multiplication
between data signal, m(t) and a carrier signal, c(t). The process yields a new signal,
v(t).
Q2
(a)
(i)
Analyze the Fourier Transform of the signal v(t) by using modulation
properties.
(ii)
Sketch the spectrum of signal v(t).
m(t) = 1
→ v(t)
c(t)
= cos w̟t
