One of the most important classes of time dependent signals are periodic signals. Periodic signals satisfy tho following signal equations, x(t) X(t) x(t+nt) for n 2,3. The periodic signals to be observed in this laboratory assignment are shown below. In all the examples A represents the amplitude of the signal and may be given as the measurement from 0 to the peak value A, Apk or can be given as the measurement between A and -A which defines a peak-to-peak...
2. A 3 KHz sinusoidal signal Phase Modulates a carrier at 245.3 MHz. The modulating tone has an amplitude of 4 volts and the phase sensitivity of the modulator is 0.5 radians/volt. a.

Exercise: Use MATLAB to generate the sinusoidal waveform: x(t) = 3 cos(1200) Consider the frequency of this sinusoid and use this information to select an appropriate time-step and time array that will allow this signal to be correctly represented and displayed on a new MATLAB figure window (display 4 periods of this wave only). Now set up an appropriate frequency array and use the fft() and fftshift() functions to generate and plot the Fourier Transform (magnitude spectra)...
Let Y (t) = sin(ωt + Θ) be a sinusoidal signal with random phase Θ ∼ U[−π, π]. Find the pdf of the random variable Y (t) (assume here that both t and the radial frequency ω are constant). Comment on the dependence of the pdf of Y (t) on time t.

There is an initial signal containing 60 Hz sinusoid of amplitude 0.8 and a 150 Hz sinusoid of amplitude 1.2 corrupted by a noise - using the randn command - (zero-mean white noise with variance of 4). Plot the noisy signal in the time domain. After that compute the Fourier transform -using the fft command of the noisy signal, compute the two-sided spectrum. Define the frequency domain f and plot the single-sided...
