Abstract :
This paper presents a technique to obtain a realization for passive ladder networks of the inverse-Chebyshev lowpass filter with all positive elements. The technique consists in the shifting of transmission zeros to infinity by means of a transformation in the complex frequency s-plane. The technique allows for multiple frequency shifts until the desired realization is obtained. Results show that there are additional improvements in group delay and in stopband attenuation
