Question

please answer the question given in the picture

a) Sketch the spectrum of the message signal x, (t) = 4 sinc(2t) cos(67t) and then find bandwidth and minimum sampling frequency. b) The signal x, (t) is time division multiplexed with the signal whose spectrum is given in Figure 1(a). Prior to multiplexing, both signals are sampled separately. If the sampling of the both signals will be done with same minimum frequency, then how the sampling frequency should be selected? X2(f) -2.5 2.5 f(Hz) Figure 1(a) c) Write the multiplexed signal xpu (t) sample values in [0-1] sn interval. What is the rate of TDM signal? Hint:Your odd numbered samples should belong to x, (t) and even numbered samples should belong to x2(t)
