Question

How many adders are needed to construct 7-bit parallel adder?

How many bits have typical full-adders ICs got?

Answer 1

(a) 7 full adders

(b)4 bits

Step-by-step explanation:

(a)A n bit parallel adder requires n full adders to perform operation.

Here we want to get 7 bit parallel adder so 7 full adders are required to perform operation

(b)These full adders perform addition of two 4bit binary numbers.
