Analog signal - Wikipedia, the free encyclopedia
An Analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e analogous to another ...

Analog signal processing - Wikipedia, the free encyclopedia
Analog signal processing is any signal processing conducted on analog signals by analog means. "Analog" indicates something that is mathematically represented as a set of continuous values. This diff...

analog signal: 1. A signal that has a continuous nature rather than a pulsed or discrete nature. Note: Electrical or physical analogies, such as continuously varying voltages, frequencies, or phases, may be used as analog signals.

Figure 4a: Analog Signal ... Telephone voice signal is analog. The intensity of the voice causes electric current variations. At the receiving end, the signal is reproduced in the same proportion. Hence the electric current is a ‘MODEL’ but not one’s voice since it is an electrical representation or analog of...

And a fundamental understanding of how analog signal transmission works must first begin with a discussion of electrical basics. To understand the ways in which an analog signal is transmitted over a circuit, it is first important to understand the relationships that make analog signal transmission possible.

Analog signals are processed by analog circuits. The principal feature of an analog circuit is its ability to process an analog signal faithfully, without distorting it—hence the expression hi-fidelity. A typical analog signal is produced at the output terminals of a microphone as someone speaks into it.

However, when a data acquisition system is transmitting low level analog signals over wires, some signal degradation is unavoidable and will occur due to noise and electrical interference. Noise and signal degradation are two basic problems in analog signal transmission.

In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape. The wave from the microphone is an analog wave, and therefore the wave on the tape is analog as well.
