带通滤波器设计指南2TUTORIAL A GENERAL DESIGN PROCEDURE FOR BANDPASS FILTERS DERIVED FROM LOW PASS PROTOTYPE ELEMENTS: PART II P art II of this bandpass filter tutorial features several examples that illustrate the general design procedure for bandpass filters using resonators and coupling methods of different types. BANDPASS FILTER DESIGN The general bandpass filter design procedure utilizes the normalized, low pass elements of the prototype filter to determine the required resonator …several examples that coupling and coupling to the external circuit, illustrate the general design that is, the source and procedure for bandpass filters load. In each case, the external source and using resonators and coupling load are assumed to be methods of different types. 50 , although the filter could be matched to o……
