An Ultrasonic Pulser/Receiver System with Extended Dynamic Range and low Distortion

摘要

The increasing sophistication of quantitative ultrasonic techniques and signal processing requires signal electronics systems having performance characteristics which are significantly better than those of conventional designs. Better performance, in terms of extended signal dynamic range, stability, bandwidth, and signal distortion, is becoming essential for many applications in the laboratory and in the field; further, software control of large automated systems often requires specialized circuit configurations, which are not available.
