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, m₂ (t) m₂ (t) (i) Transmitter (ii) If the spectrums of the two signals are given as below: IM₁(f)I (iii) 1 Channel b -10kHz a cos(80,000ft) cos(40,000ft) LPF BW=10kHz Receiver AN IM₂ (f)I 10kHz -10kHz BW-10kHz LPF What must the bandwidth of the channel be required for the system? 10kHz m₁ (t) m₂ (t) Sketch the spectrum at point (a) and (b) of the receiver. (Label all magnitudes and frequencies of the axes.) Design a transmitter to multiplex the signal mi(t) and m(t) for the receiver. (Show clearly all the details.)
