Logic gates are the basic building blocks of digital systems. They have one or more inputs and a single output, and their output is determined by the logic relationship between their inputs. Common logic gates include AND, OR, NOT, XOR, NAND, NOR, and XNOR gates, which output a 1 or 0 depending on whether the inputs are both 1, either 1, inverted, different, both 1 for NAND and NOR, or the same for XNOR.

- 1. LOGIC GATES
- 2. LOGIC GATES Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic. Based on this, logic gates are named as AND gate, OR gate, NOT gate etc.
- 3. AND GATE: AND gate(.) – The AND gate gives an output of 1 if both the two inputs are 1, it gives 0 otherwise.
- 4. OR GATE: OR gate(+) – The OR gate gives an output of 1 if either of the two inputs are 1, it gives 0 otherwise.
- 5. NOT GATE: NOT gate(‘) – The NOT gate gives an output of 1 input is 0 and vice-versa.
- 6. XOR GATE: XOR gate() – The XOR gate gives an output of 1 if either both inputs are different, it gives 0 if they are same.
- 7. NAND GATE: NAND gate()- The NAND gate (negated AND) gives an output of 0 if both inputs are 1, it gives 1 otherwise.
- 8. NOR GATE: NOR gate()- The NOR gate (negated OR) gives an output of 1 if both inputs are 0, it gives 1 otherwise.
- 9. XNOR GATE: XNOR gate()- The XNOR gate (negated XOR) gives an output of 1 both inputs are same and 0 if both are different.
