Study Notes
Logic Gates
- Logic gates are fundamental building blocks in digital circuits
- They perform logical operations on binary inputs (0 or 1) to produce a binary output (0 or 1)
- The relationship between inputs and output is based on a specific logic
- Logic gates are used in microprocessors, microcontrollers, and embedded systems
AND Gate
- An AND gate produces a 1 output only when all inputs are 1
- Otherwise, the output is 0.
- Represents logical "and" operation
- Output = A • B (A and B)
OR Gate
- An OR gate produces a 1 output if at least one input is 1
- The output is 0 only if all inputs are 0
- Represents logical "inclusive or" operation
- Output = A + B (A or B)
XOR Gate
- XOR gate produces a 1 output if the inputs are different
- Output is 0 if the inputs are the same
- Represents logical "exclusive or" operation
- Output = A ⊕ B (A exclusive OR B)
NOT Gate
- A NOT gate inverts the input
- If the input is 1, the output is 0
- If the input is 0, the output is 1
- Represents logical negation or inversion
NAND Gate
- A NAND gate is an AND gate followed by a NOT gate
- Output is 0 only if all inputs are 1
- Otherwise, the output is 1
- Output = !(A • B) (NOT (A and B))
NOR Gate
- A NOR gate is an OR gate followed by a NOT gate
- Output is 1 only if all inputs are 0
- Otherwise, the output is 0
- Output = !(A + B) (NOT (A or B))
XNOR Gate
- An XNOR gate is an XOR gate followed by a NOT gate
- Output is 1 if the inputs are the same
- Output is 0 if the inputs are different
- Output = !(A ⊕ B) (NOT (A exclusive OR B))
Truth Tables
- Truth tables show all possible input combinations and their corresponding outputs for each gate.
- Essential for understanding how a gate functions.
