MODIFICATION OF RESONANCE CHARACTERISTICS OF ULTRASONIC TRANSDUCERS BY THE DRIVING CIRCUIT

Ch. Papageorgiou, Th. Laopoulos

Abstract

A study of the resonance characteristics of low frequency ultrasonic transducers is presented in this work. The effect of the influence of the equivalent output resistance of the driving circuits on the shape of the frequency response and the sensitivity of the transducer is investigated. Theoretical presentation is accompanied by simulation analysis and verifying experimental measurements.
