Digital electronics or digital (electronic) circuits are electronics that operate on digital signals.

In contrast, analog circuits manipulate analog signals whose performance is more subject to manufacturing tolerance, signal attenuation and noise.

Digital techniques are helpful because it is a lot easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values.

A power supply is an electrical device that supplies electric power to an electrical load.

The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

As a result, power supplies are sometimes referred to as electric power converters.

Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power.

Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible power supply).

The ampere (symbol: A), often shortened to "amp", is the base unit of electric current in the International System of Units (SI).

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.

In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators.

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.

The term vibration is precisely used to describe mechanical oscillation.

Familiar examples of oscillation include a swinging pendulum and alternating current.
