Abstract
In this paper, the required measurement time to measure a transfer function with a specified accuracy is analyzed. The waiting time that is needed to balance the transient induced errors against the noise errors is calculated. This allows one to decide under what conditions broad-band measurements are faster than stepped sine measurements

Swept Sine Impulse Response Measurement

         

Module by: Edgar Berdahl,  Julius Smith

         

Summary: The swept sine measurement technique is used for measuring impulse
responses.  It has advantages when measuring weakly nonlinear systems
in that the linear and nonlinear components can be separated to some
extent.  Free, open-source software is provided in Matlab (or
Octave) and Pure Data (PD) for carrying out swept-sine
impulse-response measurements using the sound hardware found on a
typical personal-computer.
