Question: 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)

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(210 t)] cos(210t) 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
