Time for action – plotting the Bartlett window

The Bartlett window is a triangular smoothing window. Perform the following steps to plot the Bartlett window:

1. Call the NumPy bartlett function to calculate the Bartlett window.

   window = np.bartlett(42)

2. Plot the Bartlett window with Matplotlib, which is very easy.

   plot(window)
   show()

   The following is the Bartlett window, which is triangular, as expected:
