| Abstract: | For the purpose of improving transducer,we have carried out studies on generation of unioplar ultrasonic pulse. This paper use Mason equivalent circuit to calculate theunipolar ultrasonic pulses,and to studies on generation of unipolar ultrasonic pulses. Thetheoretical result and experimental result are in agreement. |
