A chirp signal, in which the angular frequency rises uniformly from Ï 0 ÎÏ/2 to Ï 0

Question:

A chirp signal, in which the angular frequency rises uniformly from Ï‰₀€“Î”Ï‰/2 to Ï‰₀+ Î”Ï‰/2 over a time T, can be written as exp(iÏ†(t)), where the phase Ï†(t) is given by

for |t| ‰¤ T/2. This signal is then passed through a delay-line, whose effect on a component of angular frequency w can be represented as multiplication by the factor
