摘要
文中提出一种可直接测量多比特数字信号频率的方法,叙述了基本原理及实施方法。此方法的特点足实施简单、成本低廉、精度高。当信号频率较高且量化的比特数较多时,上述优越性特别明显。
In this paper,a method for directly measuring multi-bit digital signal frequency is presented. This paper also describes the basic principles and the implementing method. The characteristics of this method are simplicity, low cost and high accuracy. The value of frequency of the original signal or the bit number of the digital signa increasing,the advantages of this method are clearer.
