Question

using the mixed logic design style to implement the output carry ( ) of a full adder using only 3-input nor gates.

Answer 1

The output carry of a full adder can be implemented using 3-input NOR gates in a mixed logic design style.

Step-by-step explanation:

The output carry (CO) of a full adder can be implemented using 3-input NOR gates in a mixed logic design style.

To implement CO using NOR gates, we can use the following expression: CO = (A.B) + (C_{in}.(A+B)).

This expression can be implemented using two 3-input NOR gates. Here's how:

1. Connect the inputs A and B to the first NOR gate.
2. Connect the inputs A and B to the second NOR gate.
3. Connect the outputs of both NOR gates to a third NOR gate.
4. The output of the third NOR gate will be the CO.
