In this study, Window-based computer program, named Synthesis Software, is developed for
designing filters with equal-ripple or maximally flat passbands and general stopbands by using
cascade synthesis technique in transformed frequency domain. Synthesis technique is applicable
to lumped element and commensurate line distributed element filters with Lowpass,
Highpass or Bandpass characteristics. Singly or Doubly terminated filters can be synthesized. friendly environment for typing in the parameters of the filter to be designed. This part uses
Synthesis and Plot parts as modules.
This software is based on the previous softwares developed in EEE Department of Middle
East Technical University. All the previous softwares were gathered in the well-known software
Filpro, which is in DOS environment, in Pascal. Thus, the new software is actually a
conversion of Synthesis part of Filpro from DOS environment into Windows environment in
the language C#, with some improvements in root finding algorithms for numerical conditioning.
Synthesis Software is has three parts. The first and main part is the implementation
of synthesis technique by using object oriented programming technique. In this way, synthesis
technique implementation is isolated from other parts of Synthesis Software and it can be
used by other filter design programs as a module. The second part of the program is responseplotting
section. In this part Insertion Loss, Return Loss, Time Delay, Phase and Smith Chart
responses are calculated and displayed. The last part is User Interface, which provides user
