What is exponential sine sweep?
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 a sine sweep?
A sine sweep is a sine function that gradually changes frequency over time. The sine sweep can also be called "sinusoidal sweep," "frequency sweep", or "chirp".
What is a logarithmic frequency sweep?
A logarithmic sweep spends more time at the lower frequencies and spends equal time within each octave. This is why there is a predictable, steady/constant rate of roll-off over the measured frequency range.
