Generated with the following code:

import numpy as np
import matplotlib.pyplot as plt

frames_per_cycle = 16
freq = 2
nr_frames = frames_per_cycle * freq
phase = 0
audio = np.fromfunction(lambda y : (y /  frames_per_cycle + phase) % 1 - 0.5, (nr_frames,))

fig, ax = plt.subplots(nrows = 2)
ax[0].plot(np.linspace(0, freq, nr_frames), audio, "-")
ax[0].set_title("Analog")
ax[1].plot(np.linspace(0, freq, nr_frames), audio, "o")
ax[1].set_title("Digital")
plt.subplots_adjust(hspace = 0.5)
plt.show()
