[CLO1] [15 Marks] Question 14 Design a DSB-SC modulating system to simultaneously transmit two signals having same bandwidth of 5000 rad/s as shown in the spectra below. To comply with the regulations, the spectrum of transmitted signal should not contain frequencies less then 5000rad/s, and there should be minimal spectral gap between two message signals to save bandwidth. Choose the minimum carrier frequency that satisfies these conditions. (Important to show block diagram and spectrums at each operation.) -5000 10 5000 M2(@) -5000 10 5000 Design a demodulator for the above transmitted signal to recover both message signals.
