Abstract :
A new technique is presented for maximizing the band-edge selectivity of general Chebyshev filters with minimum filter order. Based on maximizing the band-edge selectivity, the frequencies of extreme values of magnitude characteristic in the stopband are calculated in the closed form. The transmission zeros are obtained by solving a set of non-linear equations. Synthesis and design examples are given to verify the presented procedure.
