The modified Yule-Walker scheme is employed to define arbitrary transmission scattering parameter of a multiple-level band-pass filter in the discrete-time domain. Equal-length microstrips including single- and double-section stubs are used to implement the multiple-level band-pass filter. Experimental results are presented to illustrate the validity of this design method.
