摘要

本文提出一种基于电压频率变换（Ｖ／Ｆ）的数字相敏检测方法。这种方法可对被检测信号进行矢量分析。文中分析了这种数字相敏检测方法在加性高斯白噪声和谐波干扰环境下的检测性能，并给出了这种方法与常用的正交采样法的计算机模拟比较结果，此外，文中还给出了本文所提出方法用微处理器实现的结构

Abstract

Based on voltage to frequency（V/F） conversion a method for digital phase sensitive detection（DPSD） is proposed in this paper

by which a vector analysis of detected signals can be achieved.The detection performance of the proposed method

under AWGN and harmonics

is analyzed and computer simulation results are given for comparision between the well-known inphase/quadrature sampling method and the one described here.An architecture of microprocessor based implementation of the proposed method is also presented.
