We live in a world of analog signals. In digital electronics, however, there are only two states – ON or OFF. Using these two states, devices can encode, transport, and control a great deal of data. Logic levels, in the broadest sense, describes any specific, discrete state that a signal can have. In digital electronics, we generally restrict our study to two logic states - Binary 1 and Binary 0.

- What is a logic level?
- What are common standards for logic levels in digital electronics.
- How to interface between different technologies.
