Boolean Algebra is the mathematical foundation of digital circuits. Boolean Algebra specifies the relationship between Boolean variables which is used to design combinational logic circuits using Logic Gates. The truth table shows a logic circuit's output response to all of the input combinations.
The Truth Table shows the values of the circuit output for all input values.
Fig 1 is an example of four circuits that are equivalent because their truth tables are identical.
Logic gates are used to implement the following type of digital circuits.
Bank Alarm System
A bank wants to install an alarm system with 3 movement sensors.
To prevent false alarms produced by a single sensor activation, the alarm will be triggered only when at least two sensors activate simultaneously.
