English term

compander

GBK English to Slovak Tech/Engineering Telecom(munications)
Definition from Maxim Integrated Products, Dallas Semic.:
Signal processing technique which uses both compression and expansion to improve dynamic range and signal-to-noise ratio. A signal is passed through a non-linear transformation prior to transmission. A reverse of this transformation occurs at reception. The transformation is such that quiet portions are boosted and loud portions reduced. Noise is reduced because the quiet signals are louder, compared to the noise in the transmission channel. Used in digital, PCM, transmissions as well as analog applications. Dolby is a common example of a compander-based noise reduction system.
Example sentences:
This compander covers a frequency domain from 20Hz to 20KHz, the total distortions are below 1% and the signal/noise ratio is 80dB. (electroschematics.com)
Unlike traditional companders that have increasing amounts of signal distortion as the frequency becomes lower, the Syfx compander has no signal distortion at any frequency. (syfx)
We tested transmissions with two companders (DSKs) on 40 meter SSB using three ham radios to compare co-channel interference and signal quality. The third radio was used for creating an interference signal. The compander definitely helped to lessen the co-channel interference from this interfering signal transmitting at the same signal strength. (people.wallawalla.edu)

Termíny (kompandér, expandér) majú na Slovensku svoje miesto v technickej terminológii už dávno, ešte z dôb analógovej telefónie (i keď možno nemajú oporu v citovanom slovníku cudzích slov).
Jan Kolesar Nov 24, 2009:
Kompandor vznikol z fonetického prepisu francúzskeho slova compandeur. Ale v súčasnosti sa väčšina technických výrazov prekladá z angličtiny a preto sa v praxi viac zaužíval kompandér, napriek doporučeniu v slovníkoch. Nech sa vyjadria aj ostatní, ak sa mýlim, rád zmením názor.
Martin Bulla Nov 24, 2009:
Myslím, že by sme mali uvádzať tvar nachádzajúci sa v Slovníku cudzích slov. Podľa neho je správnym tvarom výraz kompandor. Už len preto, že z týchto výrazov GBK tu na Proz.com tiež vzniká slovník. A v ňom by sa mal ocitnúť výraz, ktorý má oporu v aktuálnej slovenskej slovníkovej literatúre.
