Hi all,
This is a text book question from a study course. Its asks to modify a 3 bit synchronous counter by inverting the output so that it matches the truth table below:
A B C X
0 0 0 0
0 0 1 0
0 1 0 0
0 1 1 0
1 0 0 1
1 0 1 1
1 1 0 0
1 1 1 1
I have minimised the truth table using Karnaugh tables and find that X = A/B+AC and have drawn the circuit attached.
There are probably many ways of achieving this, but as I am fairly new the dig logic topic I am sticking with simplicity.
I am unsure about my results, as its a counter circuit, which needs the output changed, is it ok to add gates, or should I be looking at trying to design a counter circuit which reproduces the truth table somehow?
Id appreciate any helpful input thanks.
