Process and system for measuring time, low error and high resolution between pulses of electrical signals.

摘要

Process and system for measuring the time between two electronic signals with high resolution using cross correlation and interpolation with the technique multitaxas ". Characterized by the measure of time with cross correlation to improve the accuracy and the interpolation technique with the multitaxas to increase the resolution of the measure of lag time between the two electronic signals.The efficiency of the process and the system proposed was verified by determining the speed of ultrasonic wave from the measure of elapsed time of their echoes, which requires high resolution, especially in the tension measurement.
