频率响应 (FR:Frequency Response): 它是对声卡的ADC和AC转换器频率响应能力的一个评价标准。人耳对声音的接收范围是20HZ-20KHZ,因此声卡在这个范围内音频信号始终要保持成一条直线式的响应效果。如果突起(在声卡资料中是用功率增益来表示)或下滑(用功率衰减)都是失真的表现. 单位dB,越接近0dB越好

【电子学】频率响应,频率特性
frequency response
n.(electronics) a response depicting the output-to-input ratio of a transducer as a function of frequency
双语例句
The frequency response function includes an aerodynamic transfer function.
频率的主函数包括主动力传递函数。
The frequency response of recording devices is a function of the relative speed of the recording medium past the head.
记录设备的频率响应是上述记录媒质经过磁头的相对运动速度的函数。
