Question

a) The highest frequency of a signal is 25kHz(Sinusoidal). If it is sampled at the following sampling interval, can you able to recover the original waveform at the receiver? Prove each case with the help of clearly labelled graphs(Plot the graphs with respect to time) i) The waveform is sampled at 20μs interval ii) The waveform is sampled at 40μs interval iii) Write a reflection on the effect of different sampling time ? in the part I and ii. b) An 10 bits single channel PCM system gives an output of 102 kilo bit per second(kbps). Calculate: i. The sampling frequency of the system. ii. The highest possible modulating frequency of the system. iii. The bit duration of the system. iv. The Bandwidth of the system. c) A channel is providing a S/N ratio of 65dB. When the bandwidth of signal is 22 KHz, the value of Eb/N0 is found to be 40dB. If same channel is used with same signal bandwidth but with a MEC_AMO_TEM_035_02 Page 3 of 11 ? Digital Communication (ELEC 20004.1) – Spring- 2021 – CW (Assignment 1) – All – QP different data rate. It is observed that the new Eb/N0 is reduced by 40% of its initial value. Calculate the new value of Eb/N0 and data rate
