这种作法已经被广泛应用，并可以用以改善市电频率成分（包括奇次谐波。）
This is fairly commonly utilized, and affects the line frequency component (and odd harmonics).
为了研究这一问题，我使用了一个滤波器组，来获得一系列固定在市电频率的信号。
To investigate this, I used a filter bank to obtain a set of signals locked to the incoming line frequency.
市电频率Hum，主要原因包括灯丝线路走线导致的不平衡；供给灯丝的电源变压器（缺陷）导致电源杂波耦合进入信号通道，等等。
Line frequency hum, primarily induced by imbalance in the filament circuit wiring, the transformer used to power the filament, coupling into the signal leads, etc.
