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 .
Analogy is a comparison or correspondence between two things (or two groups of things) because of a third element that they are considered to share. [1]In logic, it is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction.
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
High-definition television: Broadcasting using a line standard of 720 or greater. Prior to World War II, high definition meant a line standard greater than 240 lines. A CB radio with an exposed helical "rubber ducky" antenna. helical antenna A radio antenna with one or more conductive wires, wound up in the shape of a helix. A version of this ...
An arbitrary waveform generator (AWG or ARB) is a sophisticated signal generator that generates arbitrary waveforms within published limits of frequency range, accuracy, and output level. Unlike a function generator that produces a small set of specific waveforms, an AWG allows the user to specify a source waveform in a variety of different ways.
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.

An analog circuit that alters some frequency-related property of a signal. analog signal processing Generally, techniques used to alter signals that rely on voltages or currents that vary continually over a practical range. analog signal A signal whose properties (current, voltage) vary proportionally to the information transmitted.
