Monocomponent Nonstationary Signal with Constant Frequency Modulation and One-Sided Exponential Amplitude ModulationΒΆ
Generate a monocomponent nonstationary signal with constant frequency modulation and one-sided exponential amplitude modulation.
Figure 2.7 from the tutorial.
from tftb.generators import fmconst, amexpos
import matplotlib.pyplot as plt
from numpy import real
fm, _ = fmconst(256, 0.2)
am = amexpos(256, 100, kind='unilateral')
signal = am * fm
plt.plot(real(signal))
plt.xlabel('Time')
plt.ylabel('Real part')
plt.title('Constant Frequency, One-sided Exponential Amplitude')
plt.xlim(0, 256)
plt.grid()
plt.show()
