Open Ended

4. What is a Digital IC?

•Digital ICs operate at only a few defined levels or states, rather than over a continuous range of signal amplitudes.

•fundamental building blocks of digital ICs are logic gates, which work with binary data, that is, signals that have only two different states, called low (logic 0) and high (logic 1).​
