Abstract
A method to analyze the properties of ultrasonic transducer is proposed. The method is based on Hilbert-Huang Transform. The signals derived from ultrasonic transducer will be decomposed by empirical mode decomposition, and then the intrinsic mode functions can be obtained. So the marginal spectrum of each intrinsic mode functions will be calculated. The marginal spectrum offers a measure of total amplitude (or energy) contribution from each frequency value. Using those marginal spectrums and intrinsic mode functions, the amplitude and frequency properties of ultrasonic transducer can be analyzed. The proposed method was applied to analyze the properties of two ultrasonic transducers in experiment, and the results show that it is effective.
