Chirp Waveform (System Identification Toolkit)
The chirp waveform, also known as a swept sine wave, is a sinusoid waveform with a frequency that varies continuously over a certain range of values ω

In comparison to other stimulus signals, such as white noise, a chirp waveform is easier to generate and control. The following figure shows an example of a chirp waveform.
