The synthesis of critical monotonic low-pass amplitude characteristics(CMAC) is the
subject of analysis and research presented in the dissertation. Several new considerations
related to the contributions to the development of synthesis have been presented in order to:
facilitate the choice of the proper transfer function, allow cataloguing the transfer functions,
simplify the circuit synthesis procedure, and perform synthesis in the form of a state variable
continuous time active filter.
In the process of synthesis four main criteria for transfer function synthesis have been
implemented: maximally flat at the origin, maximum slope at the band-edge, maximal
asymptotic attenuation, and minimal amplitude distortion in the pass-band. For every
criterion a class of filter are generated and the coefficients of the transfer functions and are
published for the first time.
The properties of the generated classes filters which are generated in that way have been
quantitatively compar...ed for the first time. The „state-variable“ structure filters are exposed as
the one way of the systematic and simplest synthesis procedure of CMAC filters. The
procedure has been explained and the design process are exemplified. Statistical tolerance
analysis have been performed for the example solutions in order to complete the picture for
comparison.
