Butterworth - type and bessel function - type two ways are used for design of bandpass filter for receiver, and with the help of eda simulation tools, the bold plot and the group delay characteristics of the filters designed are compared
摘要採用巴特沃思型和貝塞爾函數型2種方法進行接收機帶通濾波器設計，藉助eda對該濾波器進行波特圖和群延遲特性的比較。 -
The spectral and group delay characteristics are studied and the potential uses of this type of grating for wavelength selection and dispersion compensation are discussed. a novel scheme of oadm configuration based on linearly chirped moir fiber gratings is proposed. we have designed a lcmfg to compensate dispersions for eight channels at the same time
在此基礎上，提出了一種新型的基於線性啁啾moir光纖光柵的光分插復用器（ oadm ）的結構設計方案；並設計出一種中心波長、相鄰中心波長間隔都符合itu規定的dwdm波長標準的基於線性啁啾moir光纖光柵的多通道色散補償器件。 -
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。 -
The converter mainly accomplishes changing the c - band rf to intermediate frequency 70mhz, amplifying and gaining. the thesis includes r & d of local oscillator and group - delay equalizer. the thesis overall views the historical development future trend, introduces the theories, applications and characteristics
