The paper deals with the analysis using Wavelet Packet Transform (WPT) and Fast Fourier Transform (FFT) of synthetically generated signals. The signals are initially sine waves of 10 periods with linearly decreasing/increasing magnitude M. M varies according to a constant slope G. The studied absolute difference between the final and initial values of M belongs to the set {2,5, 5, 7.5 and 10}% from...
