In this paper the author introduces a stepping motor actuating power source which improves the current-frequency ( I-f) characteristic and torque-frequency ( T-f) characteristic of the stepping motor from two aspects.

Then, based on the energy distribution of mixed signal across frequency channels, the T-F units that are considerably corrupted by noise in high frequency range are located, and they are removed from target streams.

然后，基于混合信号在频率通道的能量分布，在高频区域找出被噪声干扰严重的时频单元，并将它们从目标听觉流中去除。
