ULTRASONIC TRANSMITTER

摘要

The invention relates to an ultrasonic transmitter for operating ultrasonic transducers, with a pulse generator for excitation pulses, It is the aim of the invention to create a simple system with as great a variability as possible for an ultrasonic transmitter of this type. This aim is achieved according to the invention, in that the pulse generator encloses a digital frequency control member for the pulses to be fed to the transducer, in which at least the pulse frequency (fs) can be adjusted in the form of an administerable digital value (FW).
