Abstract :
Until the early 1970s, nearly all filter synthesis techniques were based on the extraction of electrical elements (lumped capacitors and inductors, transmission line lengths) from the polynomials that represented the filter´s electrical performance in mathematical terms. This was perfectly adequate for the technologies and applications that were available at the time, and many important contributions were made to the art of advanced filter transfer and reflection polynomial generation, and then their conversion to electrical component values corresponding to the filter technologies that were available at this time [1]-[13].
