摘　　要：在许多电子设计中,需要对一些低频信号进行跟踪及倍频。文章提出了一种全新的低频倍频器的设计方法,并对其原理及特性进行了阐述与分析。该倍频器具有跟踪、倍频及测频三种功能,它完全可由数字电路组成,易于FPGA的实现,而且可以根据设计人员的要求调节跟踪频率的范围,具有频率响应时间快、数字跟踪精度高等特点。Low frequency signals need to be traced and multiplied in some electronic designs. This pa- per gives a new method of designing low frequency multiplier by expounding the principles and analyzing the characteristics. This multiplier is completely composed of digital circuits with functions of tracing, multi-plying and measuring. Designers can adjust the range of tracing frequency based on the request Of design. It is easy to implement by FPGA with characteristics of quick frequency response and high precision of digital tracing.
