Abstract :
A new class of nonminimum-phase transfer functions with one pair of real-axis transmission zeros is described. These functions are suitable for determining the lowpass prototype networks in the design of narrow bandpass filters at microwave frequencies with small passband loss and very flat delay response over the central part of the passband.
