FULL SUBTRACTOR

 A Subtractor is a Logic that allows the subtracting of binary coded numbers. In this activity we were able to subtract binary coded numbers using the /XOR/ gates, and LED indicators.

Before assembling the circuit we need to know where the IC should be connected, therefore we first need to create the truth table and create a circuit diagram based on the results of the truth table.

After completing the first and second process we need to determine the logic gates diagram of the IC being used in the circuit, and then we simply assemble the circuit by implementing the output based on the circuit diagram and connect the wires to their designated input and output points of every element in the circuit.

Here is the schematic diagram for a 1-bit binary full subtractor:

Now, for our truth table, we obtain this:

Just like our Full Adder, we will have the same 4-bit full subtractor combination:

As for the result, we have this for our final output:
