# Implement Boolean function using 4x1 MUX

Implement F(A,B,C,D)= Ʃ(0,2,5,6) using a 4x1 MUX and inverters.

Can someone walk me through this? I'm new to the concept of multiplexers so I'm having trouble understanding this right now. Would you first create a truth table for this function? What has to be done from there?

Just a single 4:1 MUX, as in a circuit with four data inputs and then two control inputs that determine which of the four data inputs is sent to the output? In general, you can't make an arbitrary truth table with just these components, but if the entries are chosen carefully, you can.

Are you limited to one 4-1 mux?
