✔ 最佳答案
A pulse is a wave of short duraction, usually no longer than a wave period. Be aware that a 'pulse' could also be sinusoidal in form. It is the time duration, not the form, of the pulse and wave that matters.

Normally waves are described as sinusoidal.
A pulse is one type of wave in non-sinusoidal waveform that is similar to a square wave, but does not have the symmetrical shape associated with a perfect square wave.
