Digital signal generator for exciting an area of ultrasonic transducers

Abstract

The authors are part of a larger staff, lead by prof. dr. ing. M. E. Tanase that have, for a long time, studied the optimal ultrasonic investigations in elastic mediums, especially in biological mediums. The digital signal generator of sequence of voltage pulses is part of the imagistic ultrasonic system’s structure type B, that is ment to deliver required to excite the ultrasonic transducers. Its parameters are assesed with the program. For the utility of the generator in other working fields, the digital generator was designed and manufactured as a function generator. We expose the principles that we used to conceive the constitutive elements and the results of the material experiments.
