Design of RC Four-stage Active Band Pass Filters 四阶RC有源带通滤波器的设计
active band pass filter 有源带通滤波器
H-plane T-junction and E-plane transverse iris band pass filters are used in the diplexer structure. 双工器采用H面T接头和E面横向膜片波导带通滤波器。
The duplexer acts as a very broad band pass filter during receiving mode and the prearnp is a low noise wide band-width amplifer that is used to amplify the echo signals. 调谐电路对系统共振频率的漂移进行实时调谐,针对以上天线和模拟电路的功能,对天线和模拟电路进行了设计。
Then, a practical 50 Hz band pass filter is proposed, which is modulated with one cycle Bartlett window and in performances better than the classical filters adopting one cyclic Fourier algorithm. 提出了一种具有实用价值的由一周波三角窗调制实现的50Hz带通滤波器。
The signal processing system consists of a band pass filter(BPF) with center frequency of 2.856 GHz and bandwidth of 10 MHz,a logarithmic detector,a analog digital converting module,and a data acquisition program based on Labview. 带通滤波器选用中心频率为2.
