WebThe second step consists of the pre-processing approach to convert the raw signals into training samples that are made up of a set of input data with associated class labels. In addition, the pre-processing step comprises two main parts, namely noise injection and FFT representation, which are further discussed in Section 3.1 and Section 3.2. WebIn Python, there are very mature FFT functions both in numpy and scipy. In this section, we will take a look of both packages and see how we can easily use them in our work. Let’s first generate the signal as before. import matplotlib.pyplot as plt import numpy as np …
