摘要
论述了一种全数字化倍频电路的设计,并对电路的精度及工作特性进行了详细分析.该倍频器可工作在低频范围内,通过改变时钟频率,也能够工作在高频段范围.它具有捕捉速度快、跟踪精度高、相位误差小、线路简单、工作可靠等特点.与一般数字倍频器相比其误差减小一倍、输入频率范围增大一倍.
design of a wholly digital frequency multiplier(DFM)is expounded and precision and characteristic of the DFM is detailed analysed. The DFM can work at low frequency. It also has properties of quick--operating captain, high pation of frequencytracking, low error of phase, the simple circuit, working reliability and etc. The error of frequency tracking decreases one time of a general DFM and the range of input fequency increases one time of a general DFM.
