3 INPUTS X, Y, Z and 2 OUTPUTS D, B.

D=Difference,
B=Borrow.
Here Z, 3rd Input it's BORROW-IN.

3 input and 2 output is correct one.

For full subtractor, we need three input and it gives two output.

Input:a;b;cin(carry input).
Output:S(sum);Cout(carry output).

We can say full subtractor is alway one is output and another is borrow.

We can say in half subtractor one is difference and another one is for borrow.

Usman said:   1 decade ago
Can we say that one input is for subtraction and the other one is for borrow in half subtractor?

For full subtractor two inputs for two numbers and third input is clock input and o/p is two difference and borrow.

2 i/p & 2 o/p for half subtractor.

Prakash said:   1 decade ago
What are the inputs and outputs for half subtractor ?

And what about adder ?

Mahesh said:   1 decade ago
Its require 3 input and, its require 2 output; one indicate subtraction and one indicate borrow.
