HALF SUBTRACTOR Name: ___________________ Purpose: To build a half subtractor circuit that will accept a two-bit input and give the binary difference and borrow digit as the output. Theory: To subtract two single binary digits, the answer will consist of the difference and a borrow of 0 or 1. See textbook p253. A B Y X Procedure: Draw your wiring on your breadboard simulator before you wire it on the breadboard. (Don’t forget your labels) Save it on a disk Include a printout of a MM Logic circuit diagram. //home/vdimitrov/32382/91053e1a1190ed4bc9f5c3d8c1bff155d4313860.doc Page 1 of 3

Results: Complete the Truth Table A B X Y 0 0 0 0 0 1 1 1 1 0 0 1 1 1 0 0 Conclusion: 1. What do A and B represent? A and B are the inputs of the Half- Subtracter. 2. What do X and Y represent? The x and the y values are the outputs for the Half- Subtracter. (y = Value, x = Carry) Questions: 1. In terms of inputs A and B, give the Boolean equations for (a) X = ( A + EOR B) * B (b) Y = A + EOR B 2. Explain why X and Y are both high when A is 0 and B is 1. B is subtracted from A and we get 1 as the value. In order for the carry to show that this is negative, the value
