(Solved) : Q3 Adders Answer Following Questions Using Half Adders 2 1 Multiplexers Logic Gates Permit Q44121630 . . .
Q3. Adders Answer the following questions using only half adders and 2:1 multiplexers. No other logic gates are permitted. (a) Provide the circuit for a 1-bit full adder. (b) Implement a 3-bit adder using half adders and the adder designed in (a). Give the total number of half adders used. (c) Implement a circuit which checks if the output of the above 3-bit adder is 212. You should not use an adder/comparator to do this. Hint: 2:1 multiplexers can be used to implement 2-bit logic gates. Show transcribed image text Q3. Adders Answer the following questions using only half adders and 2:1 multiplexers.
