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。 -
We design the qmf based on the criteria of minimum frequency bandwidth and the qmf that possess linear phase, and give a example of a signal decomposed and restructured. 4. in the research of channel dropping filters, we use 5 rank butterworth filter to approach the digital filter. we design lc unpower netwok and rc power network. we manufacture lc lowpass and highpass filter ， and test their performance ; we simulate the appliance of the channel dropping filters in the system
4 .在頻帶分割濾波器的設計方法中，用5階巴特沃斯濾波器逼近最小頻寬正交鏡像濾波器，對無源和有源濾波器進行了模擬設計；設計並製作了無源lc低通和高通濾波器，測試了它們的性能；並對分割濾波器在系統中的應用進行了計算機模擬。 -
The complete design uses the given functions and releases the low - pass, high - pass, band - pass and the band - stop filters directly. butterworth, chebyshev and caoer filters are used for the implementations. in the fir filter designs, chebyshev and hamming windows are used for a band - pass filter
完全設計方法中我們利用函數直接設計出低通、高通、帶通和帶阻濾波器，並分別用巴特沃斯（ butterworth ）濾波器、切比雪夫（ chebyshev ）濾波器、橢圓（ cauer ）濾波器來實現，並比較了各自的頻率響應曲線。 -
Based on the testing principle of wheatstone bridge, a simple testing system is set up with two cascaded amplifiers and two cascaded butterworth lowpass filters. the varying voltage is tested by the system as the pressure is changed. experiment data are obtained, which also prove the feasibility of the design and the process flow
5 .基於惠斯頓電橋的測量原理，利用兩級放大電路和兩級巴特沃思低通濾波電路搭建了一簡單的測試電路系統，成功地檢測出了輸出電壓的微小變化值並得出了一些初步的實驗數據，驗證了晶元設計和工藝流程的正確可行性。 -
The synthesis and design of the conventional filters ( butterworth, chebshev, cauer ) ; further more, waveguide multiplexer and the general chebshev filters with transmission zeros were introduced. multipath coupling equivalent circuit are constructed and the relative phase shifts of multiple paths are observed to produce the known responses of the cascaded triplet and quadruplet sections
