ABSTRACT

We propose circuits for the implementation of a programmable pulser for phase array transducers. These provide digital control of pulse timing and firing, plus the possibility of manual setting of exciting pulse nature (simple or double), width and amplitude. Matching to the probe is thus optimized while programming enables adaptation to various types of transducers.
