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).

Double Side Band with Suppressed Carrier (DSBSC) signal under Digital Sound Processing: Amplitude modulation (AM) technology is used where the modulating signal is given as ?(?)=1+5.5cos(9600??) while the carrier is given as ?(?)=2cos(96000??)+4cos (144000??). How do you obtain the receiver carrier and the bandwidth of the recovering filter so as to recover the modulating signal?

(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 =...

An AM receiver is tuned to broadcast station at 600 kHz. Calculate the image rejection in dB, assuming that the input filter consist of one tuned circuit with a Q of 40? An SSB system transmit a peak envelope power of 100 W into a 75 ohms load. The carrier signal is modulated by two tones, with frequencies 2 kHz and 3 kHz with equal magnitude and only the lower sideband is transmitted with a suppressed carrier. Determine the average...
