LOGICAL OPERATORS.
- AND ( . )
- OR ( + )
- NOT ( ~, ! )
LOGIC GATES.
- An electronic circuit operates on one or more input signals to produce an output signal.
- Circuit which performs OR OPERATION is called OR GATE.
- Circuit which performs AND OPERATION is called AND GATE.
ELECTRICAL SWITCHES.
- Good examples to illustrate OR, AND and many Boolean theorems.
- Closed=1, open=0, ON=1 and OFF=0.
DEFINITION BOOLEAN ALGEBRA.
- The basic rules for simplifying and combining logic gates.
- Has either 2 values: true or false ( 1 or 0 ).
TRUTH TABLE.
- A good way to show the function of a logic gate.
- Shows the output states for every possible combination of input states.
- Symbols 0 (false) and 1 (true) are used in truth tables.
- A logic gate with n inputs, there are 2^n entries in the truth table.
- Circuit which performs AND OPERATION is called AND GATE.
