Title:
METHOD FOR IDENTIFYING THE TRANSMISSION BEHAVIOUR OF A SYSTEM, AND ULTRASOUND TRANSIT TIME METHOD FOR DETERMINING THE FLOW VELOCITY IN A MEDIUM
Document Type and Number:
WIPO Patent Application WO/2013/124156
Kind Code:
A3
Abstract:
A method for identifying a temporally variable transmission behaviour of a band-limited system, consisting of an emitting transducer, a receiving transducer and the associated electronics, provides that the transmission function of the system is determined by analysis of the transmission of a signal having a greater bandwidth than the system bandwidth and that a parametric model of the transmission function is formed and the model parameters are determined by means of fitting methods.
