DSB: Write the code for an m-file (script) to generate a DSB signal. The modulating (message) signal is a single tone signal with frequency 1kHz and the carrier frequency is 30kHz. Time Vector: 3001 points over range from 0 to 3ms (3 cycles of the modulating signal). Plot your original message signal both in time and its spectrum. (Note: use the cosine functions for your signals). In your report you should include the plots for the modulated signal in time...

Write a matlab code for given task Use your ‘sin’ or ‘cos’ function to generate a sinusoid wave having two components as f1 = 3kHz and f2 = 5kHz and then sample it with fs = 10kHz. Calculate its fft with zero frequency component in the middle. Plot it on a properly scaled w-axis. Specify if there is aliasing or not? If there is aliasing specify which component is casing the aliasing

Generate a baseband message signal m(t) to be a square waveform of duration 120 msec and amplitude 1 V. The sampling frequency is - = 10 . Use a carrier of amplitude 1 and frequency 600 Hz and perform the following modulation/demodulation operations: 1. DSB-SC a. modulation of the message signal m(t) b. coherent demodulation, assuming that the local carrier @ the receive-side is perfectly synchronized in frequency and phase with the transmit-side carrier. c. lowpass filtering of the demodulated...
