about

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. Although not realizable in physical systems, the transition between minimum and maximum is instantaneous for an ideal square wave.

The square wave is a special case of a pulse wave which allows arbitrary durations at minimum and maximum. 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).

Square waves are often encountered in electronics and signal processing. Its stochastic counterpart is a two-state trajectory.

The square wave differs from the sine wave in that, besides the fundamental frequency, it also contains odd harmonics.The sum of these harmonics and the fundamental give it its square shape. As you can see, its cycle is equally divided into two alternating constant amplitudes above and below the baseline. That's why it's called a symmetrical wave and, thus, a true square wave. Otherwise, if the time the wave is above the baseline differs form the time below the baseline, the wave is not symmetrical and it's called a "rectangular" wave.
