Chirp frequency
WebThe maximum Chirp Rate is 80 MHz/uSec: 80 MHz/uSec > Chirp Deviation / pulse width. For example, a pulse width of 0.1 uSec and a Chirp Deviation of 4 MHz has a Chirp … WebThe term “chirp” is sometimes also used in another context, when the instantaneous temporal or spatial frequency of some quantities other than the electric field varies. This can occur, e.g., in fiber Bragg gratings with …
