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 .
Analog electronics, circuits which use analog signals Analog computer, a computer that uses analog signals; Analog recording, information recorded using an analog signal; Functional analog (electronic), a system that fulfills the same function as another; Structural analog (electronic), a system that has the same structure as another
A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.
An analog synthesizer is a synthesizer that uses analog circuits and analog computer techniques to generate sound electronically. The analog television encodes television and transports the picture and sound information as an analog signal, that is, by varying the amplitude and/or frequencies of the broadcast signal.
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.
Analog signal processing is a type of signal processing conducted on continuous analog signals by some analog means (as opposed to the discrete digital signal processing where the signal processing is carried out by a digital process). "Analog" indicates something that is mathematically represented as a set of continuous values.
A simple analog function generator, circa 1990 A DDS function generator Sine, square, triangle, and sawtooth waveforms. In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies.
