(d) for a comparison, a high-grade collegiate dictionary may contain 1500 pages, 2 columns per page, 100 lines per column, 8 words per line, 6 letters per word and 7 bits per letter (all on average).

Generate binary data from the given graph with the process of delta modulation. Writing the output bit stream is enough. No need to draw the signal.

A BCD code is being transmitted to a remote receiver. The bits are A3A2A1A0 with A3 as the MSB. The receiver circuitry has a BCD error detector circuit that examines the received code to see if it is a legal BCD code. Design a circuit to produce 1 for any error condition.

An analog signal is to be coded by an ADC. The signal contains significant frequencies up to 3.2kHz. If the system is operated at a bit rate of 36,000 bits per second (bps), answer the following: a) To avoid aliasing, the sampling frequency must be greater than or equal to kHz b) If the signal is sampled at the Nyquist rate, what is the Nyquist frequency? kHz h c) If the signal is sampled at the Nyquist rate, the number of bits per sample is number of quantization levels is and the Note: *When you use the formula bFs L in finding b, the result must be rounded up to the nearest integer.

Four voice signals. each limited to 4 kHz and sampled at Nyquist rate are converted into binary PCM signal using 256 quantization levels. The bit transmission rate for the time-division multiplexed signal will be a) 8 kbps b) 64 kbps c) 256 kbps d) 512 kbps

A signal with 256 symbols is transmitted by 10 symbol per second. a) What is the information rate R? b) Can the output be transmitted without error over AWGN channel with B- 10 KHz and SNR 100 c) Find the SNR required for error-free transmission for part (b) d) Find the B required for AWGN channel for error-free transmission if SNR 100
