WebAug 30, 2016 · s ( x) = 1 1 + e − d ( sin ( π x)) , we get a square wave with duty cycle 50 %. By inverting the polarity of one copy of the wave and summing them (and taking the absolute value after subtracting 1 ), the phase shift of the inverted wave becomes the duty cycle parameter: ( s ( x) + s ( − x + 2 p)) − 1 WebAn equation can spell it out precisely. Where Apeak is the peak amplitude of the square wave, ƒ is frequency in Hertz, and t is time in seconds. Let’s put the equation to work. We’ll set the peak amplitude to 1 volt, and step through the first three harmonics by letting n = 1, 2, and then 3. Let’s build a square wave with a fundamental ...
