You had this question that I had to research:
We wish to synthesize a 2 to 4 decoder with active outputs low.
What is active inputs low?
Decoder Theory compliments of
Ready now to answer:
1. Establishing the truth table of the circuit.
***** 2. Determine output functions Y= f(A,B) A and B are the i
I really do not understand this question but I think the answer is:
f(Ai ,Bi) = (A*B)'
f(A,B) = (A'*B')' Union (A'*B)' Union (A*B')' Union (A*B)'
where A=B (A=i) (B=i)
f(A,B) = A'*A'
f(A,B) = A
I need to talk about this and find further research.
See that last line was that I don't understand the last part of this
question and I STILL don't understand it and it is related to the second
I don't GET ... what the hell is it talking about.
Determine output functions Y= f(A,B) A and B are the i
what is an output function?
