Ground loop current
|
In cctv this term refers to a current that is produced in a cable as a result of a difference in earth potential existing at each end of the cable. the result of this is noise (interference) introduced in the signal.

Difference, английский
- Disagreement, inequity, contrast, dissimilarity, incompatibility
- Разница; разность
- An important army term, meaning firstly the sum to be paid by officers when exchanging from the half to full pay; and, secondly, the price or difference in value of the several commissions.
Interference, английский
- Effect caused by the introduction of unwanted electrical signals into an electrical circuit. in cctv this results in "noise" in the signal or picture, which disrupts the picture.
- Extraneous energy which tends to interfere with the reception of the desired signals.
- Disturbances of an electrical or electromagnetic nature that introduce undesirable
- “artifactual increase or decrease in apparent concentration or intensity of an analyte due to the presence of a substance that reacts nonspecifically with either the detecting reagent or the signal itself.” [clsi]
- Signal
- Столкновение прав (заявляемых или патентных); приоритетный спор
- A scrambling of the content of signals by the reception of desired signals.
- Disturbances of an electrical or electromagnetic nature that introduce undesirable responses in other electronic equipment.
- A range of phenomena associated with the superposition of waves
- For light, the way that waves add together, depending on their phase. constructive interference occurs when the waves are in phase and their amplitudes add. destructive interference occurs when the waves are 180 degree out of phase and their amplitudes cancel.
- N интерференция interfix n интерфикс
- The static and other noises sometimes heard over the phone line.
- Столкновение одновременно заявляемых прав на патент
- Distortion of a light wave due to interaction with another wave
- A proceeding, conducted before the patent trial and appeal board, to determine priority of invention between a pending application and one or more pending applications and/or one or more unexpired patents under pre-aia u.s. patent law.

Ground loop insulator, английский
A transformer with no direct connection between the inputs and outputs, used to eliminate ground loop currents.
Gen-lock (external sync), английский
A method of synchronising a number of cameras in a system to ensure that they all produce fields at the same time. this is used to prevent picture "bounce" when switching between cameras and can improve the overall quality and update time of recordings wh
