Adding these harmonics to the fundamental produces a resultant wave (shown in red) that is beginning to look like a square wave, in fact adding an infinite number of odd harmonics in this way would produce a perfect square wave. 3.4.6 shows a sine wave (the fundamental) together with its 3rd and 5th harmonics.
Pls correct me if i am wrong.īut here harmonics is used for "Fig. But when the output appears little off from a sine wave we say it is distorted and this is due to presence of harmonics caused by non linear load. Thank you so much for the help!!! I was able to obtain the THD plot but still my only last doubt is as far as i read and understood harmonic distortion is something say the fundamental freq is a sine wave and we require a that proper sine wave in the output.
