Two signals, mi(t) and m2(1) (both band-limited to 10,000 Hz) are to be transmitted simultaneously over a channel using a custom frequency division multiplexing scheme. The multiplexing system is shown as below, b 58411 Channel Transmitter m₂ (t) m₂ (t) If the spectrums of the two signals are given as below: IM₁ (f) (1) (ii) (iii) a cos (80,000nt) -10kHz cos(40,000nt) Receiver LPF BW=10kHz AA IM₂ (1 10kHz -10kHz What must the bandwidth of the channel be required for the system? 10kHz LPF BW=10kHz m₂ (t) m₂ (t) Sketch the spectrum at point (a) and (b) of the receiver. (Label all magnitudes and frequencies of the axes.) (10 marks) (5 marks) Design a transmitter to multiplex the signal mi(1) and m₂(1) for the receiver. (Show clearly all the details.)
