A software unit that is a part of SOGS/SPSS, and which expands user-built commands to produce an SMS SCS related term
A machine mechanically similar to a compressor but in which a gas expands from a higher to a lower pressure doing work and undergoing a drop in temperature in the process The drop in temperature is usually, but not necessarily, the principal objective The orifice in a refrigeration system also produces an expansion of the gas and a drop in temperature, but an expander performs it more nearly isentropically, and is thus more efficient in a cryogenic process
Expanders were introduced in the EPI document of SCSI-3 Expanders are devices for doing things beyond the normal SCSI definitions that do not require a SCSI ID Examples of expanders are SCSI enhancement devices such as SCSI Converters, SCSI Bus Extenders, SCSI RegeneratoRs, SCSI repeaters and SCSI switches
A device that restores the dynamic range of a compressed signal to its original dynamic range (188)
A device that reduces the level of a signal when it falls below a specified threshold to exaggerate its dynamic range
A unit that increases the dynamic range of an audio signal Works in reverse to a Compressor
A device to be officially introduced in an X3T10 Committee report Expanders are devices for doing things beyond the normal SCSI definitions that do not require a SCSI ID Examples of expanders are SCSI enhancement devices such as SCSI Converters, SCSI Bus Extenders, SCSI RegeneratoRs, SCSI repeaters and SCSI switches
The opposite of a compressor Where a compressor takes a given dynamic change and reduces it, an expander increases it, making changes larger Expanders are used to "un-do" compression in some circuits (companding) More commonly, expanders are used for noise reduction In this application (downward expansion), a threshold is set at a level below desired audio signals, but above the noise floor When signal drops below the threshold, expansion is applied, pushing signal even further down, reducing the level of noise For example, an expander might be set up with a 1: 6 ratio This means that for every 1 dB of input level change the expander sees, it will output a 6-dB change When a signal drops below the threshold by 2-dB, the output of the expander will drop by 12-dB, similarly dropping the level of any background noise floor
A circuit to perform dynamic range expansion of an audio signal, usually in a logarithmic manner The receive portion of a companding system
A circuit that increases dynamic range by making the loudest notes louder and the softest notes softer
A transducer that, for a given amplitude range of input voltages, produces a larger range of output voltages
