The analysis of modulation wave theory has very important theoretical and actual meaning for studying nonsine alternating current.
谐波理论分析对于非正弦交流电路的研究具有重要的理论和实际意义。
2
In the production practice, will encounter a large number of non-sinewave.
在生产实践中，会遇到大量的非正弦波。
3
Though the efficiency can be enhanced when sinewave passes through non-linear loads, the sinewave distortion appears, and then harmonic current passes through loads.
