title = "Research on frequency control to ultrasonic transducer",
abstract = "The frequency control to ultrasonic transducer has two requirements. One is resonant frequency automatic following, the other is sweep frequency modulation. The first problem is solved by PLL (Phase Locked Loop) technology. The second problem is solved by DDS (Direct Digital Synthesis) technology. But both PLL and DDS have their own shortcomings. To solve these problems, the technology of PLL plus DDS is put forward. The experiment results show that this scheme is feasible.",
