受话器频响特性的素数多频快速测量

Fast Testing of Receiver's Frequency Response Using Prime Number Multi-freqency Signal

本文介绍了具有普遍实用意义的频响特性素数多频快速测量法在新研制的受话器综合测试仪中的应用情况，该方法通过采用多频合成激励信号达到快速测量；通过选择素数序列频点达到有效抑制系统非线性因素对测量准确性的影响；通过调整多频信号各频点成分的初相达到多频信号峰值因数最小化。

This paper introduces the fast freqency response testing method using prime number-multi-freqency-signal, which is used in a receiver comprehensive test instrument.Testing is made fast by using Multi-freqency-signal. Test error, which is caused by nonliearity, is minimized by using prime-number-multi-freqency-signal. The peak factor of the multifreqency signal is minimized by using TFDSA(Time-Freqency Domain Swaping algorithm)
