d) UHF 40] Answer any 4 sections () to (V) D (10) Briefly explain the following terms: a) Modulation b) Quantization c) Ground Wave e) mode ) (10) Describe the E1 standard for TDM by drawing a frame diagram and showing different components and timing information. Calculate the following: (a) Frame repetition rate (b) Data rate of each channel (c) Total data rate supported by the E1 standard. ii) (10) Given that a communication channel has a spectrum of 1,000Hz to 16,000Hz, find the maximum channel capacity if there is no noise in the system (ideal case) and 8 signal levels are used. (Hint: state the relevant theorem and give equation) iv) (10) Given the communication channel specified in (Q3-iv), find the maximum channel capacity if there is noise and the S/N = 63 in the system. (Hint state the relevant theorem and give equation) v) (10) Please determine the PAM value (normalized magnitude), give the quantized code value (PAM) and the corresponding PCM code to be used of a 4-bit code is assigned to each sample in the following signal quantization example in Fig.1 (see next page).
