Abstract

This work presents a modification to Chebyshev filter transfer functions to improve the delay response. The technique consists in the shifting of the nearest to origin maximum of frequencies, but taking special care in not modifying the normalized edge frequency ω_c. After making the change of variable in the transfer function, we obtain improvements in the group delay, furthermore, the new frequency response gives us the possibility to make an LC ladder realization to be equally terminated for even order functions
