Normal AM modulation can be generated by using a switching modulator with a bandpass filter. 1.1 Express modulating signal m(t) and carrier signal c(t) in time domain, and frequency domain. 1.2 Assume the diode switching signal p(t) is given by Part 2: Normal AM demodulation 1, p(t) = f(x) = 0, 0, Te 4 ● ≤x≤ Where T denotes the fundamental period of carrier signal c(t). Determine the complex exponential Fourier series of the signal p(t). ● Te 1.3 Evaluate the output modulated signal s(t). 1.4 Design a suitable bandpass filter to generate normal AM modulation expressed below. s(t) = 2 [1+0.8 cos(2π10³ t)] cos(2π10¹t) 1.5 Use MATLAB or Pspice software to plot the modulating signal, carrier signal, switching signal, and modulated signal in the time domain and frequency domain. Explain your results. Te 1<x< 1/ 4 2 To recover the message signal from the modulated signal, use an envelope detector. 2.1 Design the envelope detector to recover the message signal. 2.2 plot the demodulated output signal in both the time domain and frequency domain. Phase Two (Due on Thu. 18/1/2024): Bread-board Circuit Implementation Based on your analysis: Implement the normal AM modulator and Demodulator breadboard circuit. Display the modulated, and demodulated signals on an oscilloscope. Explain your results.
