Digital Circuits Digital electronics are those circuits in which the current or signals are not continuous. Digital electrical signals are gen- erated at fixed intervals and have a fixed numeric values. Microprocessors, electronic clocks, and computer parts are made using digital circuits.

Mixed-signal Circuits Mixed-signal circuits are another type of circuit. These circuits consist of both analog and digital circuits. Thus, they are also known as hybrid circuits. Such circuits are used in DVD players, radio communications, and in communication circuits, such as those of cell phones.

SCIENCE FACTS

● ● Electrons can flow in a closed circuit forever without any breakdown. ● ● The current flowing in a circuit is measured in amperes.
