Low-power/wideband transfer function measurement method and apparatus
Scientific Applications & Research Assiociates, Inc.
The invention is a method of measuring transfer functions of a physical system using a wideband excitation signal by exciting the system with a low-power, wide band input signal that has a rich frequency content over a wide band and using a stochastic process to derive a system transfer function over the excitation signal bandwidth.
