Question 1 (CLO1- PLO1, 5%) a) Define and state an example for each of the following types of communication systems. 1. Simplex (1 marks) ii. Duplex (2 marks) b) Define communication system with aid of appropriate diagram. c) Define following terminology: i. Electronic communication ii. Information Transmitter III. iv. Receiver V. Transmission medium Base band converter vi. vii. IX. Subsystem synchronization Transmitter medium Transmission impairments Noise (3 marks) (5 marks) (10 marks) d) An amplifier has gain of 55,000, which is too much for the amplification. With an input voltage of 30 μV, what attenuation factor is needed to keep the output voltage from exceeding 100m V? Let A₁= amplifier gain = 55,000; A₂ = attenuation factor; A, = total gain.
