What is a swept sine?

A swept-sine, also called a chirp, is a widely used signal for characterizing a frequency response of a linear system under test. A technique for analysis of nonlinear system (NLS) based on an exponential swept-sine signal has been first presented by Farina in 2000.

What is log chirp?

The log-sine chirp is. essentially a sine wave whose frequency increases. exponentially with time (e.g. doubles in frequency.
