I have 2 different signals and I'm trying to cross-correlate then using Python 2.7 and scipy.signal.correlate
. How do I normalize my results (such that the max amplitude is 1.0? I tried the following:
import numpy as np
import matplotlib.pyplot as plt
t = np.linspace(0,2*np.pi,num=1000)
x1 = 10*np.sin(2*np.pi*t)
x2 = np.sin(2*np.pi*t+np.pi/2)
x12 = scipy.signal.correlate(x1,x2,'full')
plt.plot(x12)
x12 / np.max(x12)
? $\endgroup$ – Pier-Yves Lessard May 25 '17 at 2:40
