The device can calculate transientharmonics (up to 50 orders) of any part of data wave, give the total harmonic distortion, each harmonic ratio and each harmonic value.
装置可以计算波形任意部分的多达50次的 暂态谐波，给出谐波总畸变率及各次谐波的含有率和谐波值。

The theoretic and simulative results show that the pro-posed system can detect the steady and transientharmonics with shorter dynamic response time and better tracing performance of filter.
理论和仿真表明，系统可检测电路稳态和暂态谐波，且缩短了动态响应时间，改善了滤波器的跟踪性能。

However, SMPS operate at high switching frequencies, and the associated transient pulses are full of high frequency harmonics that may cause electromagnetic interference (EMI).
