Homework Statement
Assuming the existence of 6 digital inputs and 1 digital output, design a schematic circuit diagram using any number of 8-1 muxs (i.e. no external gates) to satisfy the following requirements:
The output is true (1) when (inputs 1 and 2 are not the same) and at least 2 of the inputs 3,4,5 and 6 are true (logic 1).
Homework Equations
The Attempt at a Solution
I have drawn out a truth table for the mux...
A B C as the selectors
with combinations of 000-111 for 8 inputs
I also attempted to write the boolean equation for the mux...
tried to simulate a mux in Quartus using VHDL and solve it that way (but my VHDL is not very good).
There are so many variables and I do not know exactly which path I should take...
Could you give me a clue?
Also, how do you use a digital circuit to simulate "at least #" are true or false?
