Notes:
A cross-correlation method of measuring the impulse response of linear systems is presented. In theory, by using this method, the impulse response of any linear system can be obtained while the system is being used under normal operation with no significant distortion of the normal system output. A cross-correlation system was modeled and constructed using discrete components and simulation and experimental results are presented. Unfortunately, these results show that the extracted impulse response is severely distorted by the normal system input and the system noise. However, by averaging and interleaving methods, the impulse response of any linear system can be extracted with a high degree of accuracy. © 1995 American Institute of Physics.
