| Summary: | 碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 99 === Band-pass filter is a very common and important communication components, designers should not be used to filter and attenuation of the signal band to the filter frequency response curve characteristics, the majority of filters are based on Chebyshev filter . The papers use Chebyshev polynomials as a seed function, to further modify the chained filter function, through the design parameters of the coupling coefficient and coupling matrix used with the ADS and Zeland program and other computer-aided software to estimated and compared the conventional Chebyshev bandpass filter and the modified chained filtering function bandpass filter frequency response, low sensitivity characteristics.
