low-pass filtering

Compared with common audio signal processing attacks such as MP3 compression, low-pass filtering etc., they are more difficult to manage.

与mp3音频压缩、低通滤波等常规的音频信号处理攻击相比，同步攻击更加难以抵抗，已经成为研究界的一个公开难题。

The experimental results show the algorithm is robust against common audio signal processing such as MP3 audio compression, low-pass filtering, etc.

实验表明本算法对通常的音频信号处理，如MP3音频压缩、低通滤波等具有较好的稳健性。

Accelerometer readings can be jerky and noisy. Applying low-pass filtering on the signal allows you to smooth it and get rid of high frequency noise.

加速度传感器数值可能被颠簸和噪音影响。应用低通过滤器在信号上可以是它平滑，并摆脱高频噪音的干扰。
