阻帶衰減 的英文怎麼說
中文拼音 [zǔdàishuāijiǎn]
阻帶衰減
英文
attenuation in suppressed band-
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 。The performance of filters is not very good. the attenuation of stop - band is almost - 44db. the performance cannot satisfy the requirement for some application situation
其阻帶衰減大約在- 44db ，對於一些對濾波器阻帶性能要求較高的應用場合，這個數值是達不到要求的。Bessel function design simulation results show the small pass - band ups, stop - band attenuation, in the pass - band with a better group delay characteristics, which can meet the design requirements
模擬結果表明貝塞爾函數設計的濾波器通帶起伏小，阻帶衰減大，在通帶內群延遲特性較好，可以很好滿足設計要求。Applying the method of this article, we can get that the attenuation of stop - band is - 75db and the error of reconstruction is 0. 0015. the simulation program and experiment result are provided. the correctness and validity are proved
用本文的方法，在重構誤差將近千分之一的情況下，取得了較好的濾波器特性，其阻帶衰減達到- 75db ，文中給出了matlab實驗程序及結果，並通過simulink模擬，證明了這種方法的正確性與有效性。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。The specification is that the cutoff frequency must be more than 15mhz, the maximum passband ripple must be 0. 2db and the minimum stopband attenuation must be 40db
該濾波器要求截止頻率大於15mhz ，通帶最大紋波為0 . 2db ，阻帶最小衰減為40db 。High speed, high damping factor, with reduce / gain, full protect system, special heat radiator, excellent components. it can work at 2, 4, 8
本機其特性為高速度、高阻尼系數、帶衰減/增益切換等等功能、完整的保護系統，獨特的散熱設計，精良的元件，可輕松承受2 4 6 8負載。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。分享友人
