Question
A pulse is a wave:
- Of high duration
- Of short duration
- Which travels in a vacuum only
- Which travels in solids only
Hint:
Of short duration
The correct answer is: Of short duration
A pulse wave is a type of non-sinusoidal waveform that includes square waves with a 50% duty cycle and similarly periodic but asymmetrical waves with duty cycles other than 50%. It is a term used in synthesiser programming that refers to a common waveform found on many synthesisers. A pulse wave is a short-duration wave train caused by a rapid (non-persistence) vibration of the source.
