A truth table with three inputs has how many switch combinations?
Answer (2)
Three inputs have 8 possible states. Here they are:
0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1
A truth table with three inputs has 8 possible combinations, derived from the formula 2 n where n is the number of inputs. For three inputs, the calculation is 2 3 = 8 . These combinations represent all the possible states of the inputs.
