Question
Question 1 (a) Briefly explain the drawback of the following network topology and state ONE (1) application for each topology: i. Star network ii. Bus network i. Ring network. (b) A receiver circuit has THREE (3) amplifiers with absolute power gains of 3, 5 and 6 respectively, the output power of the circuit is 13 Watt, calculate: i. the total gain in dB for the amplifiers connection in cascade ii. the power input in dBm for the amplifiers connection in cascade ii. the total gain in dB for the amplifiers connection in parallel. (c) In a telephone circuit, a 50 2 resistor with 23° C temperature has connected across the input of an amplifier. The voice frequency range from 225 to 2995 Hz with a Signal-to-Noise Ratio (SNR) of 38 dB. Determine: i. the bandwidth ii. the information capacity in kbps i. the thermal noise power in dBm iv. the noise voltage applied to the input of an amplifier.
