The crest factor, which is the difference between the signal's peak and its average power, [31] is on occasions considered as a basis for the measure of micro-dynamics, for instance in the TT Dynamic Range Meter plug-in. [32] Finally, R 128 LRA has been repeatedly considered as a measure of macro-dynamics or dynamics in the musical sense.
Audio engineers use dynamic range to describe the ratio of the amplitude of the loudest possible undistorted signal to the noise floor, say of a microphone or loudspeaker. [18] Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system. For example, if the ceiling of a device ...
The measured dynamic range (DR) of a digital system is the ratio of the full scale signal level to the RMS noise floor. The theoretical minimum noise floor is caused by quantization noise. This is usually modeled as a uniform random fluctuation between − 1 ⁄ 2 LSB and + 1 ⁄ 2 LSB.
Range imaging is the name for a collection of techniques that are used to produce a 2D image showing the distance to points in a scene from a specific point, normally associated with some type of sensor device. The resulting range image has pixel values that correspond to the distance. If the sensor that is used to produce the range image is ...
The term dynamic range may mean: Dynamic range, dynamic range is a term used frequently in numerous fields to describe the ratio between the smallest and largest possible values of a changeable quantity. High-dynamic-range imaging, the intention of HDRI is to represent the wide range of intensity levels found in real scenes.
The Laser Dynamic Range Imager (LDRI) is a LIDAR range imaging device developed by Sandia National Laboratories for the US Space Shuttle program.The sensor was developed as part of NASA's "Return to Flight" effort following the Space Shuttle Columbia disaster to provide 2-D and 3-D images of the thermal protection system on the Space Shuttle Orbiter.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder , also known as a laser telemeter , is a rangefinder that uses a laser beam to determine the distance to an object.
Time-domain reflectometer for cable fault detection. A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses.
