Full scale

Recording

The term has a full scale, depending on the objective of the modulation, different meanings.

From a purely technical point of view, one can define full scale as to achieve the greatest undistorted communicable level. The greatest signal peak within a receptacle reaches exactly the headroom without distorting. This procedure has the effect that different degrees dynamic recordings played in sequence, are perceived as different noisy. To control such a full scale inertia-free program meter are required. In computer programs, this type of full scale is achieved with the function Normalize.

In the radio and television equipment full scale refers to the attainment of the nominal or reference level. The term reference level here is part of an operating concept and can be seen in direct proportion with the terms of headroom (English headroom ) and inertia of the Aussteuerungsmessers. To measure serves a VU meter, the specified properties.

In transmission chains such as television or radio to achieve an equal loudness of all contributions would be desirable. The sound technology loudness is measured with a loudness meter. Here is also the voltage reference level as a full-scale part of the operational concept. A reference level for the full scale according to loudness has been agreed is not binding, neither is there sufficient operating experience currently this device category is sufficiently widespread.

Processing

Photos whose full scale is at the reference level, should have minimal distortion. For analog devices, full scale defines the point at which its rendering properties are best. For a signal with a relatively low level noise leads to signal distortion, at too high a level to take non-linear distortion, up to oversteer. Audio Equipment for mixing is optimized for minimal distortion in the reference level.

The level indicator on an instrument shows the crossing of the full scale of a yellow / red mark. The point of the full scale is often also characterized by 0 dBr and 100%.

Alternative uses

With devices, such as loudspeakers, the level is referred to as a full scale, which can be transferred without any damage. Here, too, so that is always the voltage level meant. Thus, this definition is inconsistent with the upper statement in their application damage could occur to the unit.

Outside of audio technology, the term full scale occasionally the maximum modulation that can handle a system during normal operation.
