ECE414 Lab 4: DSB AM modulation and demodulation Description: The message m(t) is defined as: m(t) = 2t - 2, 0 ≤ t ≤ 3 m(t) = 0, otherwise This message is DSB-AM modulated with the carrier c(t) = cos(2πft), and the resulting modulated signal is denoted by u(t). It is assumed that f = 250 Hz and t0 = 0.15 s. 1. The expression for the modulated signal is: u(t) = [2t - 2] * cos(2πft) 2. Derive the spectra of m(t) and u(t): M(f) = 0.05e^(-0.05|f|)sinc(0.05f) U(f) = [0.05e^(-0.01|f|)]/[1 - 2e^(-0.01|f|)] 3. Demodulate the modulated signal u(t) and recover m(t). Plot the results in the time and frequency domains. To demodulate, we multiply u(t) by cos(2πft). The demodulated signal is given by y(t) = u(t) * cos(2πft), whose Fourier transform is given by Y(f) = 0.05e^(-0.05|f|)sinc(0.05f) - 2e^(-0.0125|f|). In order to recover the message m(t), we pass y(t) through a lowpass filter with a bandwidth of 150 Hz.
