Chirp transforms and Chirp series

open access: yesJournal of Mathematical Analysis and Applications, 2011
The theory of non harmonic Fourier series was originated by Paley and Wiener, and more recently, in a series of papers, many questions were studied. The authors introduce an integral version of the non-harmonic Fourier series, called Chirp transform.

Chirp excitation [PDF]

open access: yesJournal of Magnetic Resonance, 2017
The paper describes the design of broadband chirp excitation pulses in NMR. We first develop a three stage model for understanding chirp excitation in NMR. We then show how a chirp $π$ pulse can be used to refocus the phase of the chirp excitation pulse. The resulting magnetization still has some phase dispersion in it. We show how a combination of two
