Question

Problem 5 Implement a full subtractor using a decoder and OR gates. A full subtractor does a single-bit subtraction, subtracting Y from X. The three inputs to the device are X, Y, and $B_{in}$ (the borrow-in bit), and the 2 outputs are the difference bit D and the borrow-out bit $B_{out}$. Put a box around your final circuit, with all inputs and outputs labeled ?D $B_{out}$ $B_{in}$ X-Y XY

Step 1

The truth table will help us understand the behavior of the circuit and determine the logic gates required. Inputs: X, Y, Bin Outputs: D, Bout | X | Y | Bin | D | Bout | |---|---|-----|---|------| | 0 | 0 | 0 | 0 | 0 | | 0 | 0 | 1 | 1 | 1 | | 0 | 1 | Show more…
