Waveform: meaning, definitions and examples
📈
waveform
[ ˈweɪvˌfɔːrm ]
sound representation
A waveform is a graphical representation of the variation in a signal amplitude over time. It is commonly used in audio and electronic engineering to visualize sound waves. Waveforms can help in understanding the characteristics of sound, such as frequency and amplitude.
Synonyms
signal shape, sound wave, wave form.
Examples of usage
- The engineer analyzed the waveform for distortion.
- The waveform of the sound showed clear peaks and troughs.
- Different musical instruments produce unique waveforms.
Etymology
The term 'waveform' combines the word 'wave,' from Old English 'wafian,' meaning to 'oscillate, to sway,' and 'form,' from Latin 'forma,' meaning 'shape, appearance.' The use of the term 'waveform' in a technical context dates back to the early 20th century with the advancement of electronics and audio technology. It became particularly prominent with the development of oscilloscopes, which allowed engineers to visualize electrical signals in the shape of waves. By studying different waveforms, scientists and technicians could improve sound quality and analyze various audio characteristics. The term has since been adopted in numerous fields, including telecommunications, music production, and signal processing.
