Pade-Laplace analysis of signal averaged voltage decays obtained from a simple circuit

摘要

The Pade-Laplace method is an, interesting yet relatively unknown method for determining the exponential time constants in a decaying signal. We apply it to data from a simple electronic circuit specifically designed for investigations of signal averaging. Possible decays of the voltage include single, multi-exponential, and predominantly logarithmic. Students in our computer-interfacing course write a LABVIEW program that collects the data and performs the signal averaging. (c) 2005 American Association of Physics Teachers.
