filter attenuation 中文意思是什麼

filter attenuation 解釋
濾波衰減
  • filter : n 1 濾器，濾紙，過濾用料[砂、炭等]。2 【無線電】濾波器；【物理學】濾光鏡，濾色器。vt 過濾，用過濾...
  • attenuation : n. 1. 變薄，變細。2. 減少，減弱。3. 稀釋。4. 【物理學】衰減。
  1. Two kinds of filters are presented : by transferring the conventional waveguide cavity filter to the siw, a narrow bandstop filter is designed and simulated, get characteristic of narrow - band bandstop filtering. for example, relative bandwidth 1. 2 %, most attenuation of 48db in band. electromagnetic bandgap ( ebg ) structures present “ forbidden band ” characteristics, siw features high - pass characteristics, so bandpass filters can be composed by combing ebg and siw

    本論文提出了兩種基片集成波導濾波器結構:將傳統的腔體濾波器概念運用於基片集成波導結構，設計出了一種窄帶帶阻濾波器，對其進行模擬，得到了窄帶帶阻濾波特性，如相對帶寬為1 . 2 % ，最大衰減為48db 。
  2. The main work of the system can be divided into four main parts as the following : ( 1 ) 10. 5ghz bandpass filter the main contradiction of filter is caused by its function of dividing frequencies. in order to properly divide frequencies, not only need passband ’ s attenuation to be as small as possible and stopbands ’ as big as possible, but also need a sharp and quick change between the attenuation of passband and stopband, thus to make their diversity obvious

    這四個功能模塊分別是: （一） 10 . 5ghz帶通濾波器濾波器的主要矛盾是由它分隔頻率的功能決定的，為了使分隔理想，一方面要求通帶的衰減盡可能小，阻帶衰減盡可能大，亦即通帶和阻帶的衰減差值要盡量大;另一方面要求通帶和阻帶之間衰減的變化應盡可能快，最好是陡峭的跳變，使阻帶和通帶的分隔十分明顯。
  3. Comparisons between the acoustic performances of the air cleaners with and without filter paper illustrated that the acoustic attenuation performance has been improved due to the existence of filter paper

    通過比較不帶濾紙和帶有濾紙的空氣濾清器的聲學性能結果表明，濾紙的考慮與否對空濾器的中高頻消聲性能有很大影響。
  4. A novel e - plane metal insert waveguide filter is presented in this paper. comparing to conventional e - plane waveguide filter, great improvments have been made in stop - band attenuation of a bpf

    為了提高e面全金屬膜片矩形波導濾波器的阻帶性能，本文對濾波器的結構做了改進，採用了混合膜片的形式。
  5. ( 2 ) based on the mode of ultrasonic echo, this paper designs a frequency - dependent compensation filter to compensate the absorbed attenuation when the ultrasound transmits in a tissue

    （ 2 ）在建立超聲回波信號的數學模型的基礎上，設計了頻率補償濾波器。
  6. Through analyzing strata ' s absorbtion and attenuation, the specialty of ssf in system - one ( two ) and 24 - bit a z a / d, the scheme to improve the data acquisition system is brought forward including the design of multiple differential spectrum equilibrium filter ( mdsef ) and program control amplifier

    通過詳細分析地層的吸收衰減特性， system - one （ two ）頻譜整形濾波器及24位a d的特點，對現有採集系統提出了改進方案。其中包括對多級微分頻譜均衡濾波器的理論設計，程式控制型前置放大器的理論分析與設計。
  7. Band elimination filter. a filter that has a single continuous attenuation band, with neither the upper nor lower cut - off frequencies being zero or infinite

    帶阻濾波器。只有單個連續衰減帶寬，將在上邊帶或下邊帶頻率切斷為零或無窮大。
