The band passed and the crowd cheered. 樂隊(duì)經(jīng)過時(shí)人群歡呼起來
H-plane T-junction and E-plane transverse iris band pass filters are used in the diplexer structure. 雙工器采用H面T接頭和E面橫向膜片波導(dǎo)帶通濾波器。
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. 調(diào)諧電路對(duì)系統(tǒng)共振頻率的漂移進(jìn)行實(shí)時(shí)調(diào)諧,針對(duì)以上天線和模擬電路的功能,對(duì)天線和模擬電路進(jìn)行了設(shè)計(jì)。
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. 帶通濾波器選用中心頻率為2.
The elementary principle is to make use of the band pass characteristic of surface acoustic wave filter (SAWF) choose SAW signal matched the direction of acceleration. This plan is also a base for enlarging measure range of SAW accelerometer. 聲表面波濾波器(SAWF)是一種性能優(yōu)良的新型電子器件,本文基于SAW濾波器的帶通濾波性質(zhì),設(shè)計(jì)了一種新的SAW加速度計(jì)系統(tǒng),它不僅實(shí)現(xiàn)了判斷加速度方向的客觀需求,而且為加速度計(jì)基本量程的擴(kuò)大創(chuàng)造了條件。
