Question

The number of half adder and full adder required to add 16-bit data is

Answer 1

To add two 17 bit numbers using minimum gates, the least significant bits of both the numbers can be added using a half adder and for remaining 16 bits of both the numbers, full adders can be used. 1 Half Adder and 16 Full Adders will be required.

Answer 2

Answer:

1 half adder and 15 full adders

Explanation:

To add LSB we require a 1 half addder and rest of the bits are adding using full adders as of the Carrys generated.
