bandpass filter

基本解释

Effects of the coupling probes and tunning devices for the designed dielectric resonator bandpass filter have been investigated in the paper.
并就所设计的介质谐振器构成的带通滤波器耦合探针和调谐装置进行了实验研究。
After a bandpass filter, QDPSK signal's symbol can be divided into steady section and transition section, so the demodulation and synchronization for the signal can be realized with DFT.
经过限带滤波后的QDPSK信号的码元波形可分为稳定区与过渡区，根据这一特点可以利用DFT方法来实现信号的解调和位同步。
