Frequency synthesizer having a microcontroller |
摘要 |
<p>A micro-controller adjustably provides a scanning frequency for operating a driver for an ultrasonic device. The frequency is adjusted within a defined range until an acknowledgement signal is provided to the micro-controller to lock a currently selected frequency as the operating frequency. An indicator indicates when a frequency has been selected outside of the defined range. The device is preferably implemented as a complex programmable logic device (CPLD). <IMAGE></p> |
