What (who) is signal degradation - definition

LOSS OF QUALITY OF AN ELECTRONIC SIGNAL

Degradation (telecommunications)         
In telecommunication, degradation is the loss of quality of an electronic signal, which may be categorized as either "graceful" or "catastrophic", and has the following meanings:
Dégradation nationale         
FRENCH PUNISHMENT FOLLOWING WORLD WAR 2
Degradation nationale
The dégradation nationale ("National demotion") was a sentence introduced in France after the Liberation of France. It was applied during the épuration légale ("legal purge") which followed the fall of the Vichy regime.
Signalling         
  • A digital signal has two or more distinguishable waveforms, in this example, high voltage and low voltages, each of which can be mapped onto a digit. Characteristically, noise can be removed from digital signals provided it is not too extreme.
  • A binary signal, also known as a logic signal, is a digital signal with two distinguishable levels
  • sampling]]
  • Signal transmission using electronic signals

Degradation (telecommunications)

In telecommunication, degradation is the loss of quality of an electronic signal, which may be categorized as either "graceful" or "catastrophic", and has the following meanings:

  1. The deterioration in quality, level, or standard of performance of a functional unit.
  2. In communications, a condition in which one or more of the required performance parameters fall outside predetermined limits, resulting in a lower quality of service.

There are several forms and causes of degradation in electric signals, both in the time domain and in the physical domain, including runt pulse, voltage spike, jitter, wander, swim, drift, glitch, ringing, crosstalk, antenna effect (not the same antenna effect as in IC manufacturing), and phase noise.

Degradation usually refers to reduction in quality of an analog or digital signal. When a signal is being transmitted or received, it undergoes changes which are undesirable. These changes are called degradation. Degradation is usually caused by: distance, imitation:see Remote Control, noise, interference or EMI.
