This gist is to represent how to generate a simple sine wave using numpy package and plot the results using matplotlib.

genereate_sine_signals.py

# Import the required packages
import numpy as np
import matplotlib.pyplot as plt

plt.style.use('seaborn-poster')
%matplotlib inline

# Generate a vector with 200 sample from 0 to 20
x = np.linspace(0,20,200)
# Generate the sine wave of x variables
y = np.sin(x)

# Plot the generated singal
plt.figure(figsize=(8,8))
plt.plot(x, y, 'b')
plt.xlabel('Location (x)')
plt.ylabel('Amplitude')
plt.title('This is a sine signal')
plt.show()
