1. (30pts) The input to a system is a DC component, a message, m(t), and a carrier,
c(t). The output of the system is the square of the sum of the inputs. Determine
if it is possible to retrieve DSB-SC modulated waveform. Show your work.
2) (20pts) m(t) and an unmodulated carrier, c(t), are given below
m(t) = 2.2 cos(2л400t) – 7 cos(2л700t) +5 cos(2500) volts
c(t) = 6 cos(2л2000) volts
Sketch the amplitude spectrum for a Double Sideband Suppressed Carrier modulated
waveform. You must carefully label all axes and provide each frequency component
value (the x-value); each amplitude in Volts/Hz (the y-value). Include both negative
and positive frequencies.
