The ability of a beam smoke detector to compensate for light signal degradation due to dust or dirt. Rate of compensation is limited to insure that the detector is still sensitive to slow, smouldering fires.
Camcorder circuitry that adjusts incoming audio levels automatically, alleviating excessive image brightness and distortion of loud sounds.
A circuit that automatically governs the gain of an amplifier so that the output signal level remains essentially constant (even if there are varying input signal levels).
A feature of sound recording that moderates the recording to give a consistent signal level.
AGC is an electronic system found in many types of devices. Its purpose is to control the gain of a system in order to maintain some measure of performance over a changing range of real world conditions.
(AGC) Circuitry in a headend processing device that adjusts the gain keeping the output level constant regardless of input level.
AGC - A feedback system that changes the gain of an amplifier or the attenuation of an attenuator in response to variations in magnitude of the input signal, thereby maintaining the output signal of the system at a constant magnitude.
Is a built-in feature of every camera found on AutomatedSurveillance.com. This term refers to a circuit within the camera which regulates image brightness levels for optimum performance and highest video quality.
A circuit which automatically controls the gain of a transmitter so that the output signal level is virtually constant.
A feature of a receiver, whereby the gain or sensitivity of the receiver is changed automatically, responding to the wide range of field strength encountered in practice, to achieve optimum ease of use and fast, accurate locating.
A process or means by which gain is automatically adjusted as a function of input or another parameter.
A electronic circuit that automatically regulates the gain of a signal due to a input or within specified parameters.
A circuit which automatically controls the gain of an amplifier so that the output signal level is virtually constant for varying input signal levels.
Circuitry that automatically adjust the signal to proper strength.
A compressor with a very long release time used to keep the volume of the audio very constant.
The AGC is a system the speech processor uses to manage sounds of different loudness. The child with a cochlear implant does not have a wide range of sound tolerance, as does a person with hearing. The AGC ensures that very loud and very soft sounds are processed accurately so that they fit into the range of hearing of the implant user.
When the light falling onto an imaging device reduces to a certain level, there is insufficient light to create a full level video signal. AGC acts to increase the amount of amplification in these conditions to bring the signal up to the required level. As well as amplifying the video signal, additional noise can be introduced, and the signal to noise ratio reduced. The result is frequently a very much degraded signal and poor picture on the monitor.
A system to control the gain, or the increase in the amplitude of an electrical signal from the original input to the amplified output, automatically.
A circuit that continuously adjust the recording amplifier gain to maintain a relatively constant recording level.
A circuit that adjusts the gain of a stage so that the volume is constant even though the input signal may vary over a wide range.
This is a feature of many CCTV cameras that helps keep the strength of the output signal constant, even when the light level changes. In other words, it boosts the signal strength at low light levels, and caps it at higher levels.
An electronic circuit used by which the gain of a signal is automatically adjusted as a function of its input or other specified parameter.
Camcorder circuitry that monitors sound levels and adjusts audio recording levels accordingly, compensating for changing sound conditions.
A process by which gain is automatically adjusted as a function of input or other specified parameter.
Automatic gain control is a method to control the amount of brightness seen in the image. Typical method is increasing or decreasing the gain on a camera to a median level set by the user.
A circuit used to vary radar receiver gain for best reception of signals that have widely varying amplitudes.
Automatic gain control (AGC) is an electronic system found in many types of devices. Its purpose is to control the gain of a system in order to maintain adequate performance over a range of input signal levels.
