In electromagnetics, an operation converting the vector electromagnetic wave to a scalar time series proportional to either the amplitude or the power of the wave, with or without an accompanying angular time series. A crucial aspect of detection is: the signal-to-noise ratio after detection is the square of the signal-to-noise ratio before detection.
The separation of low-frequency (audio) intelligence from the high-frequency carrier.
the detection that a signal is being received
determining that an application that has been launched, and correctly identifying its main window, so it can be monitored and controlled. Due to intricacies of the Windows programming environment, instancing complications, and the fact that many applications are not well-behaved, detection is a non-trivial problem for application launchers. Montage employs general heuristics, coupled with application intelligence to achieve reliable detection over a wide range of applications. Montage also supports a feature called auto-detection, where some types of pre-existing openings are automatically detected, as indicated by a distinctive highlighting of their Shortcuts.
The process of obtaining an inspection signal that is recognized as coming from a defect or anomaly. An in-line inspection tool can detect only those defects that produce signals that are both measurable and recognizable. Not all defects are detectable with all inspection systems.
1. The identification, at a stated level of probability, of the presence of a signal or phenomenon with certain characteristics. Less formally, a signal may be said to be detectable if it is observable under ordinary circumstances. 2. In radio, radar, and lidar, the conversion of a radio frequency or light signal to an IF signal, or an IF signal to a video signal, accomplished in a detector or mixer.
In general, detection is the extraction of intelligence from a carrier signal in a communication system. Note that this may be either an overt signal, as in a conventional radio broadcast, or a covert signal, as in steganography.
