离散余弦变换(DCT)具有优于傅里叶变换、哈尔变换等正交变换的高度解相关性(apfft fir filter design)

针对交交变频器 除产生5、7、11、13次谐波外，还产生旁频，谐波内容多的主要特点，进行了 滤波器装置方案选择，确定滤波器形式，并对滤波器参数进行了工程设计计算。 TCR+FC型Svc通过采用单独的相一相控制能调节三相电源的容抗和感抗来 补偿轧机系统的不平衡，从而降低35KV供电电网的损耗。(In addition to produce5,7,11,13 harmonic, also produced by frequency, harmonic content of main feature, undertook Filter device selection, determine the filter, and filter parameters for the calculation of Engineering design. TCR+FC Svc through the use of separate phase to phase control can adjust the capacitance and inductance for three-phase power supply Compensation system of rolling mill of imbalance, thereby reducing the power consumption of 35KV. )
