1. The problem statement, all variables and given/known data Build a circuit that either adds or multiplies two 4-bit numbers based on a control input C(C is 1 add, C is zero multiply). Numbers are positive and negative so use two's complement. You can use muxes, Full Adder Circuits, and logic gates 2. Relevant equations Multiplier circuit= Adder Circuit: 3. The attempt at a solution So, I have built both the Full Adder(for the addition part) and the multiplier. However, I dont know how to use the muxes to get the input switching if control is 0 and 1. Since the mux only has one output, I dont understand how to connect the two circuits together. Any help is much appreciated!
