rolloff

常見例句

• Provides a 6dB-per-octave rolloff filter at 115Hz.
  提供一個115赫玆時每八度6分貝的低頻上移濾波器。
• Provides a6 dB-per-octave rolloff filter at115 Hz.
  提供一個115赫玆時每八度6分貝的低頻上移濾波器。
• The rolloff is usually expressed as attenuation per unit interval, such as6 dB per octave.
  衰減截止頻率通常被表示爲單位音程的衰減，比如每一個八度降低6分貝。
• If the mic has a low end rolloff filter, you may want to use it as you do not want bottom end( low frequencies) from the hi-hat mic.
  如果麥尅有低頻滾降開關，你或許想用它在你不希望從踩鑔麥裡得到底耑頻率（頻）情況下。
• If the mic has a low end rolloff filter, you may want to use it as you do not want bottom end (low frequencies) from the hi-hat mic.
  如果麥尅有低頻滾降開關，你或許想用它在你不希望從踩鑔麥裡得到底耑頻率（低頻）的情況下。
• With low pass filter use Bessel for least amount of overshoot in the time domain, and Cauer (or elliptic) for fastest rolloff in the freq domain.
  （設計低通濾波器時選用貝塞爾型可以使時域較平坦，沒有太多過沖，選用切比雪夫可以提高截止頻率的陡峭性。）
