电磁传感器输出信号易受到各种噪声的干扰,需要检测调理电路输出信号的信噪比,以达到衡量调理电路好坏的目的,针对这一问题,设计了一种基于D S P的简易式频谱分析仪。实验测试结果表明,该分析仪操作方便,精度较高,且相对于频谱仪成本更低,完全达到了预期目的。
Electromagnetic sensor output signal vulnerable to a variety of noise interference, the need to detect the conditioning circuit output signal to noise ratio, in order to measure the conditioning circuit is good or bad purpose, in view of this problem, designed a simple DSP-based spectrum analyzer . Experimental results show that the analyzer is easy to operate and has high precision and lower cost than the spectrometer, which fully meets the expectation.
