roll-off frequency

基本解释

There is no peaking in the response but simply a smooth roll-off above the natural frequency.
響應期間無高峰期，衹是簡單的，在固有頻率上平滑的跌落。

Running a transformer into the wrong load will alter its high-frequency roll-off and square wave response.
接上錯誤負載會改變其高頻産生滾降及方波形狀。
This figure shows that the power response is very smooth throughout the whole frequency range, and the controlled off-axis roll off of the tweeter.
這幅圖表明，頻率響應是非常平滑地貫穿整個頻率範圍和高音喇叭的受控離軸滾降。
