常見例句Provides a 6dB-per-octave rolloff filter at 115Hz. 提供一個(gè)115赫玆時(shí)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(gè)115赫玆時(shí)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(wèi)單位音程的衰減,比如每一個(gè)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(guān),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(guān),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(shè)計(jì)低通濾波器時(shí)選用貝塞爾型可以使時(shí)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。) 返回 rolloff
