rolloff

常见例句

• Provides a 6dB-per-octave rolloff filter at 115Hz.
  提供一个115赫兹时每八度6分贝的低频上移滤波器。
• Provides a6 dB-per-octave rolloff filter at115 Hz.
  提供一个115赫兹时每八度6分贝的低频上移滤波器。
• The rolloff is usually expressed as attenuation per unit interval, such as6 dB per octave.
  衰减截止频率通常被表示为单位音程的衰减，比如每一个八度降低6分贝。
• 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.
  如果麦克有低频滚降开关，你或许想用它在你不希望从踩镲麦里得到底端频率（频）情况下。
• 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.
  如果麦克有低频滚降开关，你或许想用它在你不希望从踩镲麦里得到底端频率（低频）的情况下。
• 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.
  （设计低通滤波器时选用贝塞尔型可以使时域较平坦，没有太多过冲，选用切比雪夫可以提高截止频率的陡峭性。）
