So which one is appropriate? Is a square wave produced up of thé summation of discóntinuous frequencies at thé base plus every other odd harmonic up to infinity OR will it possess a constant frequency range with Several frequency content between the harmonics? Here is definitely one more, but it will be a Youtube video: Lf we do the Fourier TRANSFORM of the square wave we can use the picture below to visualize it: It is the Rate of recurrence then a third of the 3rchemical harmonic, 5th of the 5th harmonic and therefore on on to forever. If you appear at the over picture, it shows you the fairly insignificant Fourier Collection growth of a squaré wave. What is certainly a more accurate rendering of the rate of recurrence component of a squaré wave? The Fouriér Transform or á very large expanded Fourier Series.
