English term or phrase: compander

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 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
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

معالج الشوشرة

Definition from Maxim Innovation delivered:
معالج الشوشرة ، هو جهاز لمعالجة الإشارة باستخدام كل من الضغط والتمدد لتحسين المدي الديناميكي و نسبة الإشارة إلي الشوشرة.

Example sentence(s):

Dolby is a common example of a compander-based noise reduction system. يعد دولبي مثالا شائعا يعمل بنظام معالج الشوشرة لتقليل الشوشرة . - Maxim Innovation delivered
The Syfx compander was specifically designed with this in mind, resulting in a unique wide band compander that provides a clean natural sound regardless of the amount of compression or expansion being performed. ومع أخذ هذا الأمر في الإعتبار، فقد تم تصميم معالج الشوشرة من طراز إس واي إف إكس تصميما خصيصا مما نتج عنه الحصول علي معالج شوشرة يوفر صوتا طبيعيا نقيا بصرف النظر عن كمية الضغط أو الدفع التي تم تنفيذها - The Syfx Solutions
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 وعلي العكس من أجهزة معالج الشوشرة التقليدية والتي ينتج عن استعمالها تغييرا في الإشارة، بسبب خفض التردد ، فإن معالج الشوشرة من طراز إس واي إف إكس لا ينتج عنه أي تشوه في الإشارة في أي تردد من الترددات. - The Syfx Solutions

جهاز تحسين الإشارات

Definition from New Oxford English Dictionary:
a device that improves the signal-to-noise ratio of an electrical signal by compressing the range of amplitudes of the signal before transmission, and then expanding it on reproduction or reception.

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
