We even saw how we can synthesize an audio file from a periodic function such as the cosine function. In this tutorial, we will see how we can do additions to signals, multiplying signals (modulation), and applying some basic mathematical functions to see their effect on the original signal. +在过去的指导教程中【previous tutorial】(https://www.howtoforge.com/tutorial/how-to-read-and-write-audio-files-with-octave-4-in-ubuntu/)，　我们看到了读，写以及重放音频文件的简单步骤，我们甚至看到如何从一个周期函数比如余弦函数合成一个音频文件。在这个指导教程中，我们将会看到如何 ### Adding Signals
