Sweep (signal processing)

from Wikipedia, the free encyclopedia
A 15 second sweep (chirp) sine tone from 20 Hz to 21 kHz

A sweep is an alternating voltage of constant amplitude whose frequency periodically and continuously sweeps through a specified range, similar to a chirp . In terms of high frequency technology, it is a frequency-modulated signal with a relatively low modulation frequency and an adjustable frequency deviation . It is preferably used to make the transmission curve of filters visible, because it replaces the slow point-by-point registration. The corresponding device is also called a wobble generator .
