What is a logic circuit?

What are "analog signals" and "digital signals"?

A digital signal is something that is represented by a series of jumping values, such as a digital clock.
Digital clocks change numbers every minute and every second to show the time.
An analog signal is something that changes without interruption.
Analog watches show time with the long hand, short hand, and second hand, and the second hand is always in continuous motion.

The digital signals mentioned earlier are expressed as numbers (binary numbers) represented by "0" and "1".
In addition, circuits that handle analog signals, which are continuous information, are called "analog circuits".
A circuit that handles digital signals, which are skipped information, is called a "digital circuit".
The advantage of using digital signals is that they are accurate and do not degrade easily, so digital signals are used in computers.

What is a logic circuit?

A logic circuit is a circuit that performs logical operations and is also called a digital circuit.

Logical operations are operations performed between numbers (binary numbers) represented by "0" and "1".
Logic circuits are used in the calculation and data storage of signals in various electronic devices around us.
Basically, you can create circuits with various functions by combining three types of circuits: AND, OR, and NOT circuits, which will be introduced later.
