Description
A sine wave whose frequency increases exponentially with time can be used to make fast, high-resolution measurements of the impulse response of a system. Sweeping the frequency exponentially has the bonus effect of separating in time the higher-order nonlinear responses of the system. This allows the linear response of the system to be measured in the presence of harmonic distortion, and allows the distortion itself to be characterized. In this talk, the theory of the method, and its implementation in a commercial audio analyzer, will be described.
