1- Explain the process of multiplexing at the transmitter and demultiplexing at the receiver 12 marks] (draw the block diagram) 2- Three voltage amplifiers are cascaded with gains(ratios) A1, A2 and A3. The gain of the second stage (A2) is three times the gain of the first stage(A1) and the gain of the third stage (A3) is twice the gain of the second stage (A2). Input voltage to the first stage is 50mV and the final output voltage (output of the third stage) is 10V. Find the voltage gain of the second stage in dB. 1- Design a band pass filter using LPF and HPF (use only R and C with correct values) BW-10khz, and fcl. =100khz [2 marks] [2 marks] 1- Explain the process of multiplexing at the transmitter and demultiplexing at the receiver 12 marks] (draw the block diagram) 2- Three voltage amplifiers are cascaded with gains(ratios) A1, A2 and A3.
