Question

what is wave pulse?​

Answer 1

A pulse wave is a special non-periodic waveform that typically has one major crest. In some cases, when it is accompanied by several minor sub-harmonic crests, where it is called a wave packet.

A pulse wave is often associated with a single sudden motion, impact, or even explosion. It usually has a sinusoidal shape, but in electronics there are also square and rectangular pulse waves.

As with other waveforms, a pulse has a velocity and amplitude. Since there is primarily only one crest, there is no frequency or true wavelength, although the width of the pulse relates to wavelength.
