Title: Generator for controlling an ultrasonic transducer

Abstract: A generator for controlling a transducer by means of sinusoidal wave trains is constituted by the association in series of a generator for producing wave trains formed by a whole number of half-cycles of periodic signals and of a filter which is tuned to the frequency of the periodic signals.
