Abstract
The paper presents a high-accuracy method to measure the peak-to-peak value of short pulses that are received by piezoceramic transducers, o pening new applications for ultrasonic sensors. By employing a digital technique, 12-bit accuracy is achieved for a transducer with 2 MHz ce ntre: frequency. In the first step the signal is digitized; in the sec ond step a fast digital comparator determines the peak-to-peak value, The complete digital part could be integrated in a single integrated c ircuit.
