Study Notes
- Boolean algebra involves variables and expressions with two values (0 or 1) and basic operators like AND, OR, XOR, and NOT.
- Precedence of operators is determined by parentheses, NOT, AND, and OR/XOR.
- Multiplicative and additive identities are important in Boolean algebra.
- Common reductions of sums and products of Boolean expressions exist.
- Basic logic gates include AND, OR, NOT, XOR, NAND, and NOR.
- Timing considerations are important in logic design and simulation.
- Transistor-transistor-logic (TTL) chips are used for practical logic implementation.
- TTL chips come in different sizes and can be mapped to different logic levels.
- Normal logic signals have logic 0 < 0.8V and logic 1 > 2.0V.
- Inverted logic signals have logic 0 > 2.0V and logic 1 < 0.8V.
