摘要
提出并设计实现了一种数字信号处理方法,从理论和实际两方面与小波去噪方法进行了比较,利用MATLAB工具进行仿真的基础上,对该方法进行了速度上的优化,并在TMS320VC5402处理器上编程实现了该方法。将该方法用于自主开发的变压器绕组测试仪中,实际效果明显,测试精度提高了一个数量级。
An algorithm appropriating for TDT, which is based on FIR filtering, is proposed in this paper. The algorithm is compared both theoretically and practically with wavelet algorithm, optimized for speed by utilizing FDA tools of MATLAB and implemented on fix-point DSP TMS320VC5402. It achieved striking effect by utilizing the algorithm in the transformer distortion tester, whose accuracy is consequently raised remarkably.
