1·The notch filter proposed is used to attenuate the adjacent channel interference in the Loran-C receiver.

本文设计的陷波器用于衰减罗兰C接收机的邻道干扰，而且其调谐是在微机管理下处自动进行的。

2·Because capacity of channel is limited by interference. Especially for the interference from the same channels and the adjacent channels.

由于信道的容量是由干扰所限定的，尤其是同信道干扰和邻信道干扰的影响更为严重。

3·It is very important problem to achieve adjacent channel duplex in radio communication, that result in to eliminate the large signal blocking interference from local transmitter in reciever.

实现邻道双工通信，即消除本地发射机对接收机所产生的强信号阻塞干扰，是无线通信领域急待解决并有着十分重要意义的问题。
