How does the Gibbs Phenomenon effect the choice of the kth harmonics for bandwidth selection?(adsbygoogle = window.adsbygoogle || []).push({});

Basically, I have plotted a square wave using the fourier series analysis for choosing the kth harmonics. As, I increase the kth harmonics the oscillations increase. What is the smallest harmonic i can go to that is still an accurate representation of the signal. Or does it not matter.

Confused

Thanks
