Question
In certain cases, in an embedded system, a logic circuit and its truth table might be derived from a situation. By
using logic circuits and truth tables, it makes it easier to understand how something might work.
Example:
An automated House has an alarm system wherein the buzzer sound when an intruder tries to open the door or
window. The said house has two doors and two windows. Draw a logic circuit and its truth table to explain this
situation.
