Question 22 Chip 74161 Often Can Be Configurated As Below On The Left To Function As A Counter And The Truth Table Is 1 (34.47 KiB) Viewed 22 times

QUESTION 22 Chip 74161 often can be configurated as below on the left) to function as a counter, and the truth table is provided below on the right. For example, the circuit is connected such that LD'=EP=ET=1. DO=D1=D2=D3=0. If RD=1, the output 03020100 counts upward naturally whenever the chip is triggered properly, but if RD=9, the output will be reset back to all-zero state. Now let us assume the output is initially at 0000 74151 Truth Table 09 CP FO DO DI D2 D3 Бр ET D Q0 01 92 92 c 0 11 Х 2 LD EP ET Output state X X X Set to 0000 0 XX Set to initial 1 0 1 Not changed 1 Xo NC but C-0 1 1 1 Counts CP CP COUNTER 1 1 1 1 XX 2 (1) Please derive the states of output 03020100 as a function of triggering clocks. (Note: not necessary to write/sketch the output waveforms) (8 pts) (2) What is the modulus of the counter for the circuit? (2 pts)
