It can constrain frequency response of filter Banks to form null at zero frequency point and to obtain minimum side lobe area.
它可强制滤波器组的频率特性在零频形成零点并使旁瓣面积最小。
The zero transfer point can be set arbitrarily by appropriately selecting transmitting periodic time T and number N, and it is advantageous to eliminate some interference in some frequency points.
适当选择发射周期T和周期数N就可以随意设置梳状滤波器的零传输点，有利于消除某些频率的干扰；
Through electrostatics and examples of low-frequency alternating current and direct-current circuit, the problem of zero potential point is queried and clarified.
通过静电学、低频交流、直流等电路实例，质疑了电势零点问题，并对此进行了澄清。
The frequency, amplitude, zero-point of signal generated by generator can be adjust continuously.
信号发生器所产生的波形的频率、幅值、零点均为连续可调。
In addition, line mode and zero-mode voltage wave cross each other at the point of fault which causes the natural frequency "aliasing".
此外，故障电压行波于非对称短路点发生线模与零模行波相互交叉透射，致使故障电压自然频率“混叠”。
