衰减失真 meaning in English

attenuation distortion

The mathematic models of sampling and reconstruction are analysed respectively , and an important conclusion is got , that oversampling can decrease high frequence distortion of d / a output signal and the difficulty of designing lowpass filter . as a result the signal quality is improved
分析了采样和重构的数学模型,得出了一个重要结论:过采样可以减少d / a输出信号的高频端衰减失真,可以降低低通滤波器的设计难度,从而提高波形质量。
