Consider a square wave f(x) of length 2L. Over the range [0,2L], this can be written as f(x)=2[H(x/L)-H(x/L-1)]-1, (1) where H(x) is the Heaviside step function. Since f(x)=f(2L-x), the function is odd, so a_0=a_n=0, and b_n=1/Lint_0^(2L)f(x)sin...
Fourier Series: Square WaveAlain Goriely

So, a decent definition of the square wave is required. I think rise time should at least be 100x faster. What do you think? I think we generate square in Fourier series of sines, so the rise time will define what the highest frequency will have to be, isn't it? steep sizes of ...
This example shows how the Fourier series expansion for a square wave is made up of a sum of odd harmonics. Start by forming a time vector running from 0 to 10 in steps of 0.1, and take the sine of all the points. Plot this fundamental frequency....
Square wave functions are often used in computer science and electrical engineering. For example, it’s used in engineering tomodel forcesacting on a mechanical system or in an electric circuit. References Braithwaite, C. (2014).General Inner Product & Fourier Series. Advanced Topics in Linear Al...

Square waves are equivalent to a sine wave at the same (fundamental) frequency added to an infinite series of odd-multiple sine-wave harmonics at decreasing amplitudes. Computer algorithms exist which are able to sample waveshapes and determine their constituent sinusoidal components. TheFourier Transf...
