(1) What are the reasons behind the need of modulation for radio transmission, i.e., why not directly transmit the original signal? Q2) A carrier signal with frequency f. Hz is double-sideband suppressed carrier (DSB-SC) amplitude modulated by a triangular shaped message signal, m(t), plotted below (Fig. Q2). The DSB-SC amplitude modulated signal is then passed from a band-pass filter with center frequency fc-Im and bandwidth 2fm where fm =...
