"WebJul 22, 2009 · The collection of sine-wave-frequency components and their amplitudes is called the spectrum. Each component is called a harmonic. The zeroth harmonic is the DC value. For the special case of a 50% duty-cycle ideal square wave, the even harmonics have an amplitude of zero. The amplitude of any harmonic can be calculated as 2/(p x n). " - Duty cycle of square wave

WebA square wave is approximated by the sum of harmonics. In this particular SPICE simulation, I’ve summed the 1st, 3rd, 5th, 7th, and 9th harmonic voltage sources in series for a total of five AC voltage sources. The fundamental frequency is 50 Hz and each harmonic is, of course, an integer multiple of that frequency. WebThe series of square wave output pulses produced have a cycle time (T) equal to approximately 2 (0.693)*RC or 2lin (2)*RC. The output waveform frequency (ƒ) is therefore equal to: 0.722/RC. So for example, if we want to generate a 1kHz output square-wave waveform, then R = 3.3kΩ and C = 220nF using preferred component values.
