Определение waveform в Английский Язык Английский Язык словарь
(audio) The representation of an audio signal, stored in analog or digital form as a plot of amplitude versus time
A graphical representation of a wave obtained by plotting some characteristic of the wave (such as amplitude), versus time
the line's movement away from the baseline on an EKG in either a positive or negative direction; a graphical representation of cardiac electrical activity
The graphical representation of a wave, showing variation of amplitude with time
The shape of a sound produced by an oscillator that determines the timbre of a sound Different waveforms include sine, pulse, sawtooth, square, and triangle waves
The representation of an audio signal, stored in analog or digital form as a plot of amplitude versus time
A graph of the level of air compression or rarefaction that is how sound is shown in the display of a wave file editor (such as Blaze Audio Wave Creator) Usually there is a horizontal line in the middle of the display representing no compression or rarefaction The line representing the sound goes up as air becomes more compressed and down as it becomes less compressed
A graph of a signal's sound pressure or voltage level versus time The waveform of a pure tone is a sine wave
A signal, either sampled (digitally recorded) or periodic, being generated by an oscillator Also, the graphic representation of this signal, as on a computer screen Each waveform has its own unique harmonic content See oscillator
A graph showing the amplitude of a sound over a particular interval of time Any portion of that interval is a sample
The waveform is the shape of a time domain signal as seen on an oscilloscope screen It is a visual representation or graph of the instantaneous value of the signal plotted against time Inspection of the waveform can sometimes reveal information about the signal that the spectrum of the signal does not show For instance a sharp spike or impulse and a randomly varying continuous signal can have spectra that look almost identical, while their waveforms are completely different In machine vibration, spikes are usually caused by mechanical impacting, while random noise can be caused by the advanced stages of bearing degradation
A plot of any variable (e g pressure, flow, or displacement) changing as time progresses along the horizontal axis; also known as a time-series
