Narrow band transmission link ultrasonic variable delay measurement procedure for plastic manufacture uses cross correlation of transmitted and reference path signals

A narrow band transmission link ultrasonic variable delay measurement procedure uses Fourier transform techniques to cross-correlate a broadband white noise input signal with known transmission function and the same signal sent in parallel through a direct connection or a filter with known time dela...
