Logic Gates & Truth Tables+50 
Logic gates are fundamental building blocks in digital electronics that perform basic logical functions such as AND, OR, and NOT. Each gate processes binary inputs (0s and 1s) to produce a specific output. Truth tables are tabular representations that list all possible input combinations and their corresponding outputs for a logic gate or circuit. Together, logic gates and truth tables are essential for designing and analyzing digital systems and computing devices.

💡 Key Takeaways
- Identify and describe common logic gates (AND, OR, NOT, XOR) and their symbols.
- Read and construct truth tables to determine outputs for all input combinations.
- Analyze simple digital circuits by applying logic gate functions and predicting results.
- Translate between Boolean expressions and gate-level diagrams to understand circuit behavior.
❓ Frequently Asked Questions
What is a logic gate?
A digital device that applies a Boolean function to inputs to produce a single output.
What is a truth table?
A table that lists all possible input combinations and the corresponding outputs for a logic gate or circuit.
How does an AND gate work?
Output is 1 only if all inputs are 1; otherwise the output is 0.
How does a NOT gate work?
Inverts the input: 0 becomes 1, and 1 becomes 0.
What is a XOR gate?
Outputs 1 when the inputs differ (for two inputs, exactly one input is 1); for more inputs, it’s 1 if an odd number of inputs are 1.
