Logic gates are fundamental components of digital circuits that perform basic logical functions
AND Gate
The AND gate outputs a high signal only when all inputs are high
OR Gate
The OR gate outputs a high signal if at least one input is high
NOT Gate
The NOT gate inverts its input signal
Logic gates are represented by standardized symbols in circuit diagrams, making it easier to recognize and interpret their functions
The XOR gate outputs a high signal if the inputs are different
The XNOR gate outputs a high signal if the inputs are the same
The NAND gate outputs a low signal only when all inputs are high
The NOR gate outputs a high signal only when all inputs are low
Truth tables are a systematic way of listing all possible input combinations and their corresponding outputs for a logic gate or circuit
Truth tables are a critical tool for understanding and designing logic gates and circuits
Truth tables for AND and OR gates show their respective output behaviors based on different input combinations
Simple logic gates like AND, OR, and NOT are used to create basic control systems and decision-making circuits
More complex logic gates like XOR and NAND enable the construction of arithmetic units, memory storage, and other advanced functionalities in computers
Understanding how logic gates can be combined to form complex circuits is crucial for applying this knowledge in real-world scenarios
