The square wave is a special case of a pulse wave which allows arbitrary durations at minimum and maximum amplitudes. The ratio of the high period to the total period of a pulse wave is called the duty cycle. A true square wave has a 50% duty cycle (equal high and low periods). See more A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. In an … See more The square wave in mathematics has many definitions, which are equivalent except at the discontinuities: It can be defined as simply the sign function of … See more As already mentioned, an ideal square wave has instantaneous transitions between the high and low levels. In practice, this is … See more • List of periodic functions • Rectangular function • Pulse wave • Sine wave • Triangle wave See more Square waves are universally encountered in digital switching circuits and are naturally generated by binary (two-level) logic devices. Square waves are typically generated by metal–oxide–semiconductor field-effect transistor (MOSFET) devices due to their rapid … See more Using Fourier expansion with cycle frequency f over time t, an ideal square wave with an amplitude of 1 can be represented as an infinite sum of sinusoidal waves: The ideal square wave contains only components of odd … See more • Fourier decomposition of a square wave Interactive demo of square wave synthesis using sine waves, from GeoGebra site. • Square Wave Approximated by Sines See more WebFourier Series SquareWave.
