I'm required to implement a function
F = ~ABC~D + ~A~B~C~D + ~ABC + B~CD
using a 3x8 Decoder and any other additional combinational logic.
How can I implement this function if there are 4 variables (
ABCD) in the expression but only 3 inputs in my 3x8 Decoder?
If I take only
ABC as my 3 inputs on my decoder how can I include
D to complete my function.
