Answer:

Explanation:

Sum of 1st, 3rd, 5th, 7th and 9th harmonics approximates square wave. The end result of adding the first five odd harmonic waveforms together (all at the proper amplitudes, of course) is a close approximation of a square wave.

The ideal square wave contains only components of odd-integer harmonic frequencies (of the form 2π(2k − 1)f). Sawtooth waves and real-world signals contain all integer harmonics. A curiosity of the convergence of the Fourier series representation of the square wave is the Gibbs phenomenon.
