Definition that contains waveform
- distortion a change (usually undesired) in the waveform of an acoustic or analog electrical signal; the difference between two measurements of a signal (as between the input and output signal)
- sampling measurement at regular intervals of the amplitude of a varying waveform (in order to convert it to digital form)
- clipper (electronics) a nonlinear electronic circuit whose output is limited in amplitude; used to limit the instantaneous amplitude of a waveform (to clip off the peaks of a waveform)
- limiter (electronics) a nonlinear electronic circuit whose output is limited in amplitude; used to limit the instantaneous amplitude of a waveform (to clip off the peaks of a waveform)
- jitter small rapid variations in a waveform resulting from fluctuations in the voltage supply or mechanical vibrations or other sources
- sine wave a wave whose waveform resembles a sine curve
