Electronic device

Electronic device may refer to any electronic components such as integrated circuits, resistors, capacitors or other. It also refers to any assembly of the above components in an electronic circuit.
Electronic circuits and components can be divided into two groups: analog and digital. A particular device may consist of circuitry that has one or the other or a mix of the two types
Most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits. Analog circuits use a continuous range of voltage as opposed to discrete levels as in digital circuits.
One rarely finds modern electronic devices that are entirely analog. These days analog circuitry may use digital or even microprocessor techniques to improve performance.

Computers, electronic clocks, and programmable logic controllers (used to control industrial processes) are constructed of digital circuits. Digital Signal Processors are another example.
