e.g. To implement the function F(A, B, C)= Σ (1, 2, 5, 7) using MUX using different variable as selection variable. Let’s now take the variable B for input lines and A & C for selection lines. The min terms with B in compliment form are 0, 1, 4, 5 and the min terms with B in un-complimented form are […]

Q: Boolean function Implementation using MUXes
Q-How to implement any Boolean function using MUX? Ans: While implementing any function using MUX, if we have N variables in the function then we take (N-1) variables on the selection lines and 1 variable is used for inputs of MUX. As we have N-1 variables on selection lines we need to have 2 N-1 to 1 […]
Q: HIGHER MUXes from LOWER MUXes
Q- Implement (a) 8 to 1 MUX (b) 16 to 1 MUX using 4 to 1 MUX. Ans: (a) Select lines are abc2 Following is the 8 to 1 multiplexer from 4 to 1 multiplexer (b)Select lines are abcd2 Following is the circuit for 16 to 1 MUX
