摘要

一个谐振信号可以通过A/D变换后做有限长度的数字卷积测量出它的频率。本文推导了一种能够测量线性调频信号中心频率及其线性调频系数的卷积测频算法。根据所得到的鉴频特性分析和讨论了信号诸参数对鉴频特性的影响

并且给出了这种数字卷积测频算法的测频精度。

Abstract

The frequency of a resonance signal can be measured by finite length digital convolution method. In this paper

a convolution frequency discrimination algorithm which can measure the center frequency of a linear frequency modulation signal and its linear frequency modulation coefficient is derived. The influence of signal’s parameters on frequency-discrimination characteristics is analyzed and discussed

and the precision of the convolution frequency discrimination algorithm is given.
