band trap

基本解释

The selectivity is reasonably good, even at the high end of the band. A wave trap can be used to null nearby stations.
即使在频率高端，此线圈仍能保持良好的选择性。添加陷波器可以减小强台的干扰。
Combined with a water-based attractant derived from human sweat (collected from a wrist band), the trap mimics the scent, moisture, and temperature profile of a sleeping body.
再结合上从人体汗液（从手腕中来的）来的水性引诱剂，这个引诱器就能模拟和一个睡着的人体一样的情景、湿度和温度。
A band pass filter and a trap filter made up of the filer circuit which filtrate the noise and interference effectively. The signal is enlarged by the amplifiers in the middle and the end class.
滤波电路由一个四阶低通滤波和一个二阶高通滤波组成的带通滤波器以及陷波器组成，可有效滤除噪声及干扰；
