# 3. Generate the Fourier series approximation def fourier_approx(x, n_terms): total = 0.0 for k in range(1, n_terms + 1, 2): # only odd harmonics total += (4 / (hv.pi * k)) * hv.sin(k * x) return total

When downloading software for your HT Weierwei VEV 3288S device, make sure to take the following safety precautions:

# 5. Plot both the original and the approximation hv.plot(data, x='x', y=['square_wave', 'fourier_approx'], title='Fourier Approximation (15 terms) of a Square Wave', legend=True, style='square_wave': 'color': 'black', 'linewidth': 2, 'fourier_approx': 'color': 'steelblue', 'linestyle': '--')

If the official manufacturer software is unavailable or difficult to use, the open-source software is a popular alternative for programming this radio.
