| Abstract: | A method of ultrasonic guided-wave signal generator design is introduced. A torsion modal is choosed and designed in accordance with the characteristics of the desired signal and using ATmega32, AD9851 and DAC0832 to design signal generator. Simulation results show that this method is feasible. |
