Square wave Wikipedia

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

The most fundamental sound is the sine wave, characterized by a single frequency without any harmonics. A sine wave can be easily recognized by ear, as it sounds very pure, almost like a whistle. In 1822, French mathematician Joseph Fourier discovered that any waveform could be broken up as a combination of sine waves with different amplitude

Why and How to Control Brushless DC Motors DigiKey

Figure 3: Practical sinusoidal control implementations don’t drive each phase with a pure sine-wave voltage. Instead a saddle-shaped voltage is applied which results in a sine-wave differential voltage between two terminals, phase-shifted by 120˚ for commutation. The result is higher torque and speed for a given voltage and improved efficiency.
