| Abstract: | A new mean frequency synthetic technique is proposed in this peper. Two most practicalimplementation methods are given too. The feature of the mean frequency synthetic technique is theunstabillty of instant frequency and less error of mean frequency.The mean frequency synthesizer isexcellent for its simple circuit and fast frequency switching. The mean frequency synthesizer which usesfrequency divider given here is successfully used in the B mode scanner designed by the authors. |
| Keywords: | frequency synthesis mean frequency synthesis digital scan converter fastfrequency switching |
