compander การใช้

• A nearly perfect Shindler Compander replaced the modified version.
• A nearly perfect Shindler compander replaced the modified version.
• The two most popular compander functions used for telecommunications are the ?-law functions.
• A 12-bit 30 kHz stereo device using a compander to extend the dynamic range.
• In Sweden, Televerket invented a different stereo broadcasting system called the " Compander System ".
• To undo this effect, the uses a multiband compander ( compressor / expander ) with dynamically adjusted compression / expansion.
• The final compander achieved a very mild gain error recovery due to the natural truncation rounding error caused by twelve bit arithmetic.
• The final compander achieved a very mild gain error recovery due to the natural truncation rounding error caused by 12-bit arithmetic.
• However, it became apparent that a single-band compander without sliding-band technology, which was protected by Dolby patents, suffered too many audible artifacts.
• The original proposal in 1974 used a state-of-the-art 24 kbit / s Delta Modulator with a single integrator and a Shindler compander modified for gain error recovery.
• The original proposal in 1974, used a state-of-the-art 24 kbit / s delta modulator with a single integrator and a Shindler Compander modified for gain error recovery.
• Finally, the released High & thinsp; Com system, which was marketed by Telefunken since 1978, worked as a broadband 2 : 1 : 2 compander, achieving around 10 dbx.
• In April 1974, the resulting " RUSW-200 " prototype led to the development of a sliding two-band compander by Ernst F . Schr鰀er of Telefunken Grundlagenlaboratorium, Hannover since July 1974.
• The electronic circuit that does this is called a "'compander "'and works by compressing or expanding the dynamic range of an analog electronic signal such as sound recorded by a microphone.
• A similar system named High Com FM was tested in Germany between July 1979 and December 1981 by IRT . It was based on the Telefunken High Com broadband compander system, but never introduced commercially in FM broadcasting.
• It was found the modified compander resulted in a less than perfect step size at most signal levels and the fast gain error recovery increased the noise as determined by actual listening tests as compared to simple signal to noise measurements.
• The idea of a compander for consumer devices was based on studies of a fixed two-band compander by J黵gen Wermuth of AEG-Telefunken ELA, Wolfenb黷tel, developer of the Telefunken four-band audio compander for professional use.

• In the late 70s there was also the German Telefunken-made HighCom NR system, a broadband compander, which was technically very advanced and reached a signal-to-noise ratio in the range of a CD ( approximately 100 dB ).
