Use the Amplitude Modulation property of the Fourier Transform to modulate x(t) to the carrier signal m(t). x(t) = t*exp(-100t)u(t), m(t) = cos(2*π*500t). Then show demodulation of the result.

Let m(t) = cos wmt denote the message signal to modulate with wm = 200 Hz. The carrier frequency is given by We = 100 Hz. You will perform modulation and demodulation of double sideband-suppresed carrier (DSB-SC). 1. Modulate m(t). (4 pts) Note: Denote the result of modulation as Smod(t). 2. Demodulate Smod(t). (6 pts) Note: Denote the result of modulation as Sdem(t). Note: To get full credits, strictly mark on m(t) recovered.

An information signal is of the form s(t) = sin(2*pi*t)/t. The signal amplitude modulates a carrier of frequency 10Hz. Find and sketch the Waveform and Fourier transform of the transmitted signal before and after AM modulation. For AM modulation you can consider the simple case of DSB format (or double-sideband suppressed carrier modulation).
