| 摘 要： | 针对跳频通信中DDFS固有噪声的特点，提出了利用变通带PLL电路将其滤除的方法，设计了DSP控制的多VCO宽频带PLL电路，并讨论了应用该电路实现对大范围宽频带跳变信号的跟踪问题，从而解决了更大频率范围内PLL对信号的跟踪锁定能力。

| Abstract: | Aiming at the direct digital frequency synthesis (DDFS)noise's characteristic in frequency hopping(FH),communication the way filtering the noise is proposed using the changeable frequency band PLL circuits. Amulti-VCO wide frequency band PLL circuit controlled by DSP is designed. The circuit can be used in tracking and locking wide-band hopping signal in order to solve the PLL capturing the signal in more wide range. |
