5. What are two methods to generate single-side band AM signal. If the modulating signal (message) has DC omponent, which method you will choose? Why? could you please answer this in a complete brief explanation?

How do neurons in the oculomotor nuclei signal amplitude versus direction of an eye movement?

A DSB signal is squared to generate a carrier component that may then be used for demodulation. (A technique for doing this, namely the phase-locked loop, will be studied in the next chapter.) Derive an expression that illustrates the impact of interference on this technique.

Write a MATLAB program to generate a Gaussian window and apply it to a signal as follows: 1)Generate a time vector from 0 to 1 seconds with an interval of 0.001 second 2)Generate two sinusoid signals with a frequency of 90 Hz and 100 Hz, respectively, and add them together 3)Generate a Gaussian window and apply it to the combined sinusoid signal 4)Plot an overlay of the original signal and the windowed in the same figure 5)Add a legend to...

a – 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: the Matlab examples 6.1 and 6.2 will help, but use the cosine functions for your signals instead of sine...

Generate a signal composed of two square waves, the first has a 14 Hz and the second has a 55 Hz frequency. Both waves are sampled at 2 kHz for 200 ms. Duty cycle for the first wave is 40% while the second’s is 35%. Show the signal with and without adding white Gaussian noise with a variance of 1/100 in matlab

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...

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...
