Aim :- To study about logic circuits and assemble using discrete components.
Materials required:- Diode 1N4001, Resistor 1kΩ, LED, Transistor BC 547
Theory:- There are three basic logic circuits. They are AND gate, OR gate, and NOT gate. These gates can be used for assembling the secondary logic gates like NAND gate, NOR gate, EX-OR gate, EX-NOR gate etc. These gates are used for comparing different logic conditions and are the basic building blocks of digital computer. The truth table of the logic gates are as below.
