Study Notes
Logic Gates
- NOT Gate: Inverts the input signal (0 becomes 1, and 1 becomes 0)
- AND Gate: Outputs 1 only if all inputs are 1
- NAND Gate: Outputs 0 only if all inputs are 1. The output is the inverse of the AND gate.
- OR Gate: Outputs 1 if at least one input is 1.
- NOR Gate: Outputs 0 if at least one input is 1. The output is the inverse of the OR gate.
- XOR (EXCLUSIVE OR) Gate: Outputs 1 if exactly one input is 1.
- XNOR (EXCLUSIVE NOR) Gate: Outputs 1 if both inputs are the same (either both 0 or both 1).
Truth Tables
- Truth tables are used to illustrate the output of each logic gate based on the input combinations.
- For example, the truth table for the AND gate shows that the output is 1 only when both input A and input B are 1.
- Similar truth tables exist for each gate, defining the output for each possible combination of inputs.
