A maximum-length LFSR Is a counter constructed from a shift regiater with feedback to the serial input arranged so that the shift register goes through a maximum aequence of states. For an N-bit register this can be ahown to be a maximum of 21 states. Such a counter is attractive because it involves very little complexity even for a quite large count. For example, a 32-bit counter only involves the shift-register and a single 4-input XOR-gate. 3-bit LFSR A 3-bit LFSR using the equationX Xis shown at right. The OR-gate (marked with ) can be used to force a 1 at Xa without upsetting the usual operation. kicker What happens if the counter is in an initial state of "000? Why is the kicker input necessary? Clock PRBS 3-bit maximum-length LFSR Xạ = X, e Xo Analyee the behaviour of circuit - R should not be necessary to use a state table. State Dlagram for 3-bit LFSR Draw the state diagram and determine the two possible sequences for the 3-bit LFSR assume kcker-0. Use this to complete the following timing diagram. dock

2. Describe what you understand by overcurrents and indicate the protection devices that can be used for this purpose. What do you know about selectivity and parity between protections? Justify your answer.

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…
