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).
Amplitude modulation: double side band supressed carrier (DSB-SC) why is DSB-SC used for radio signals? which frequency components would carry useful information and which ones would cause unnecessary interference?
The AM signal supplies 150w of carrier power when it is modulated by a single sine wave to a depth of 70%. Suppose the total transmitted power increases by 10% when another sine wave simultaneously amplitude modulates the carrier. Determine the modulation index of the second index.
1. In the demodulation DSB-SC AM signals, there is a need for a phase-coherent or synchronous demodulator for recovering the message signal from the received signal. That is, the phase of the locally generated sinusoid should ideally be equal to the phase of the received carrier. What are the ways by which a sinusiod at the receiver can be generated phase-locked to the phase of incoming carrier signal ? Explain with the aid of block diagrams, and discuss their advantages...
