An obstacle existed in the past to simulating distributed parameters by means of a Tee‐network. This obstacle was the requirement to represent impedance functions having negative slope, such as — cosecantwl/c. Such a representation is not possible with passive elements. However, this can now be easily done in several ways. One way is to use lumped impedance elements combined with active circuits, to produce negative components. Another way is to use a desk‐top calculator in conjunction with an equivalent‐circuit analysis program that uses lumped elements, positive or negative. People who like circuits obtain a certain additional insight from this circuit approach, an insight which is not given by the usual analysis methods. The method is applicable to electromechanical transducer simulation, vocal‐tract simulation, and woodwind instrument simulation. Some graphical solutions to a transducer problem, automatically obtained in a few minutes, will be shown.
