1·If the drums will be hit medium to hard, you'll usually want to enable the mic's built-in attenuation ( pad ) switch. This helps minimize the chance of distortion.

如果鼓被越来越有力度的击打，我们经常会希望把麦克内置的衰减开关打开，这样会帮助减少失真的机会。

2·The results show that the system improved the VGA signal attenuation and distortion, achieved high-quality, long-distance transmission.

实验结果表明，该系统有效改善了VGA信号的衰减和失真现象，可保证信号的高质量、长距离传输。

3·The blind equalization algorithm is equanimous and the characteristic of convergence is not influenced by distortion of channel, it is fit for equalizing deep attenuation channel.

该算法具有镇定性，其收敛性能不会受到失真信道的影响，适用于均衡衰落性严重的信道。

4·The three-dimensional information of objects is enormous. When the data was transmitted, the error would be occurred in communication lines because of attenuation, distortion and noise.

由于实物的立体信息大，而且在数据传输过程中，由于衰减、失真和噪声，会使通信线路上的信号发生错误。
