| 摘要: |
| 本文介绍一种加快频率合成器跳频速度的新方法,该方法能确保环路的初始频差在快捕带以内,使环路迅速捕获锁定。同时,这种方法降低了对VCO性能的要求,只要在VCO振荡频率的范围内,都能保证环路实现快捕。本方法硬件结构简单、容易实现,并有较大的灵活性,在未来工程中将具有广泛的应用前景。 |

| () |
| Abstract: |
| This paper will discuss a new way to speed frequency hopping of frequen-cy synthesizer. This way will assure that loop circult is locked in a very short time.After the ring circuit out of locking, it can revise the control voltage of VCOautomatically to suit new work condition and to make frequency synthesis beinglocked in a very short time again. In this way, hardware is very simple, implemen-tation is casy and there is larger flexibility. It will have wide application prospectin future electronic engineering. |
