A good example is software, formed by analogy with hardware; other analogous neologisms such as firmware and vapourware have followed. Another example is the humorous [17] term underwhelm, formed by analogy with overwhelm. Some people present analogy as an alternative to generative rules for explaining the productive formation of structures ...
Transmission of information by changing the magnitude of a carrier signal, for example sending sound by radio. analog circuit A circuit where currents and voltages vary continually within some practical range, in proportion to some signal. analog filter An analog circuit that alters some frequency-related property of a signal. analog signal ...
Analog Describes non-digital electronic devices that deal with analog signals, devices (electronic or otherwise) that display a readout analogously (i.e., clocks, gauges), or more colloquially, non-electronic means of accomplishing a task:
An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal , the instantaneous signal voltage varies continuously with the pressure of the sound waves .
The analog data path between the connector and the analog-to-digital converter in the analog input subsystem. [c] analog output channel amplifier An amplifier attached to one or more analog output channels, that adapts the output signal range of the digital-to-analog converter to the signal level necessary to control the technical process.

Also AM radio or AM. Used interchangeably with kilohertz (kHz) and medium wave. A modulation technique used in electronic communication where the amplitude (signal strength) of the wave is varied in proportion to that of the message signal. Developed in the early 1900s, this technique is most commonly used for transmitting an audio signal via a radio wave measured in kilohertz (kHz). See AM ...
There are notable non-electrical analog devices, such as some clocks (sundials, water clocks), the astrolabe, slide rules, the governor of a steam engine, the planimeter (a simple device that measures the surface area of a closed shape), Kelvin's mechanical tide predictor, acoustic rangefinders, servomechanisms (e.g. the thermostat), a simple mercury thermometer, a weighing scale, and the ...
Analogue electronics (American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term analogue describes the proportional relationship between a signal and a voltage or current that represents the signal.
