What outputs are generated by the decoder circuit below?

Solution

for 011 input:

2⁰+2¹=1+2=3

S0 D3=1, others outputs are 0

a) is answer

for next 000 input

D0=0, others outputs are 1, since the decoder output are active low logic

a) is correct answer.

for 110 input

D6=0 others outputs are 1, since the decoder output are active low logic

a is correct answer

for next 011 D3=0, others output are1

since the decoder output are active low logic

a is correct answer.

for Mux, its inmplemnt m(1,2) so a is answer
