Problem 1: Consider the binary code 01101001. Draw the pulse code waveforms for the following signaling formats. RZ, RB, Split phase (Manchester), Split phase (Mark), NZR(L), NRZ(M) and NRZ(S). Problem 2: The information in an analog signal voltage waveform is to be transmitted over a PCM system with an accuracy of t 0.1 % of the peak-to-peak analog signal. The analog voltage waveform has a bandwidth of 100 Hz and an amplitude range of 10 to + 10 Volts. a. Determine the minimum sampling rate required. b. Determine the number of bits in each PCM word. c. Determine the minimum bit rate required in the PCM system. d. Determine the minimum absolute channel bandwidth required for the transmission of the PCM signal. Problem 3: If the following pulse train represents a TDM signal for 4 messages that are sent as pulse amplitude modulation (PAM). If each message is band limited to and sampled at 50% above the Nyquist frequency. 10 11 13 H Time (msec) a. What is the ratio of the system clock frequency to the message maximum frequency b. If these pulses are passed through a raised-cosine filter whose roll-off factor is 0.75. Determine the resulted signal bandwidth.

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3. The first support should be installed at the wall. ft ( m) from 4. The second support should be installed at from the wall. ft ( m) 5. The final support should be installed at the wall. ft…
