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 Q3Q2Q1Q0 counts upward naturally whenever the chip is triggered properly; but if RD'=0, the output will be reset back to all-zero state. Now let us assume the output is initially at 0000. 74161 "0 DO DI D2 00 重重 Q2 EP ET Truth Table OD PET Output state X 0 XXX Set to 0000 10 XX Set to initial Х 1 Not changed Xixo NC buto 11 Counts CP CP COUNTER (1) Please derive the states of output Q3Q2Q1Q0 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)
