Synthesis of Some Distributed RC Networks.
Abstract
A certainibuted RC structure can be used to obtain rational open-circuit transfer impedances. In addition, one of the driving-point impedances turns out to be rational. Hence, one of the open-circuit voltage transfer functions is also rational. Furthermore, by considering various subcircuits and distributions of resistance and capacitance it is possible to realize other ra tional open-circuit voltage transfer functions and rational short-circuit transfer admittances. Connecting these networks in series extends the class of functions realizable with such struc tures. Using a basic distributed RC network along with an external resistor and capacitor, it is possible to obtain a null in the open-circuit voltage transfer function over a certain re stricted range of frequencies. However, the shape of the notch is shown graphically to be a function of the null frequency. A lossy dielec tric in the distributed network is found to shift this range of frequencies upwards and alter the notch characteristics in much the same way as in the low-pass filter. (Author)
