Non-sinusoidal waveforms
From Wikipedia, the free encyclopedia
Non-sinusoidal waveforms are waveforms that are not sine waves. While a sine consists of a single frequency, non-sinusoidal waveforms can be described as being made of multiple sine waves of different frequencies. These "component" sine waves may, or may not, be multiples of a fundamental or "lowest" frequency. The frequency and amplitude of each component can be found using a mathematical technique known as Fourier analysis.
Non-sinusoidal waveforms are important in, for example, mathematics, music and electronics.
Examples of non-sinusoidal waveforms include square waves, rectangular waves, ramp waves, triangle waves, spiked waves and sawtooth waves.
