Extensions to the theory of time delay spectrometry

Time delay spectrometry (TDS) is a technique used to measure both frequency and time responses of acoustic and electrical systems. TDS theory is presented in both intuitive and mathematical terms. The theoretical limitations of current TDS technology are described. A new extension to TDS theory is introduced which has the potential to significantly improve TDS measurements. Implementation issues are addressed and expressions for the system error are derived. The results of computer simulation are presented.
