2. 80+4N television stations are to be transmitted through a single fiber-optic cable using uncompressed PCM and TDM. Each station comprises one 22 kHz audio channel sampled at (1+0.2N) times the Nyquist rate and encoded at a bit depth of 12 b/Sa, plus one 2.0 MHz video channel sampled at the minimum rate. The video signal must be transmitted with an accuracy of better than (20/1²)%. a) Find the (minimum) bit depth of the video signal. b) Find the bit rate associated with a single television station, including both audio and video. c) Find the minimum bandwidth of the total multiplexed PCM signal.

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.
