A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value.
Delay line memory is a form of computer memory, now obsolete, that was used on some of the earliest digital computers.
A digital delay line is a discrete element in digital filter theory, which allows a signal to be delayed by a number of samples.
Echo suppression and echo cancellation are methods used in telephony to improve voice quality by preventing echo from being created or removing it after it is already present.
An electrical network is an interconnection of electrical components (e.g. batteries, resistors, inductors, capacitors, switches) or a model of such an interconnection, consisting of electrical elements (e.g. voltage sources, current sources, resistances, inductances, capacitances).
In engineering, electromechanics combines processes and procedures drawn from electrical engineering and mechanical engineering.
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields.
Electronic filter topology defines electronic filter circuits without taking note of the values of the components used but only the manner in which those components are connected.

The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers.
An inductor, also called a coil, choke or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.
Kerosene, also known as paraffin, lamp oil, and coal oil (an obsolete term), is a combustible hydrocarbon liquid which is derived from petroleum.
Laurens Hammond (January 11, 1895 – July 1, 1973), was an American engineer and inventor.
Lithium bromide (LiBr) is a chemical compound of lithium and bromine.
Magnetostriction (cf. electrostriction) is a property of ferromagnetic materials that causes them to change their shape or dimensions during the process of magnetization.
Multipath interference is a phenomenon in the physics of waves whereby a wave from a source travels to a detector via two or more paths and, under the right condition, the two (or more) components of the wave interfere.
An oscilloscope, previously called an oscillograph, and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that allows observation of varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time.
Phase Alternating Line (PAL) is a color encoding system for analogue television used in broadcast television systems in most countries broadcasting at 625-line / 50 field (25 frame) per second (576i).
Phase is the position of a point in time (an instant) on a waveform cycle.
Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress.
Propagation delay is a technical term that can have a different meaning depending on the context.
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
