An L-shaped band elimination filter on the T-shaped joint part is also used for restricting the resonance of the frequency multiplication of the first resonance frequency.

位于T形接合部上的L形带阻滤波器亦用来抑制第一谐振频率的倍频的谐振。

The basic idea using array sweeping to suppress harmonic interference is to reasonably design each sub-sweeping frequency band that can reach the goal of elimination of harmonic interference.

利用组合扫描压制谐波干扰的基本思想就是合理地设计各个子扫描频宽，达到消除谐波干扰的目的。

Band-pass filter often used in anti-jamming devices, in order to receive a valid signal within the band, while the elimination of high frequency and low frequency interference and noise.

带通滤波器经常用于抗干扰设备中，以便接收某一频带范围内的有效信号，而消除高频段和低频段的干扰和噪声。
