- 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. Maxim Integrated Products, Dallas Semic.
- Example sentence(s)
- 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
by - 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
by - 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

- Expander je součástí zařízení kompander (také compander, compex tj. spojení kompresor-expander) [1][2], které jsou využívány pro zlepšení poměru mezi užitečným signálem a rušivými signály při zpracování, přenosu a záznamu. Signál je komprimován kompresorem, zpracován či zaznamenáván (během tohoto procesu přistupují rušivé signály) a následně expandován. Komprese i expanze je možná zároveň v celém kmitočtovém pásmu, nebo pouze v jeho určitých částech, nebo ve více pásmech separátně. Wikipedia - by pisek

- Gli elaboratori di dinamica sono una famiglia di apparecchiature elettroniche che operano
essenzialmente sul livello o ampiezza del segnale audio, in modo variabile a seconda della gamma
di livelli e della distribuzione spettrale dello stesso.
L’adozione di elaboratori di dinamica è finalizzato tipicamente ad una ottimizzazione del segnale in
relazione alle caratteristiche del mezzo di trasferimento che si intende impiegare oppure delle
apparecchiature inserite nell’impianto di diffusione sonora.
I due più comuni esempi di questa famiglia di processori elettronici sono il compressore e
l’espansore di dinamica. Il compander è un apparato in grado di svolgere entrambe le funzioni
(COMPANDER = COMPresso+expANDER). Audioprofessionale - by Maria Luisa Dell'Orto
- Example sentence(s)
- I sistemi wireless analogici convenzionali utilizzano un compander (un dispositivo di compressione/espansione di dinamica) per ampliare il range dinamico della trasmissione. - Sony
