DOWNLOAD EBOOKA novel electrical circuit designed according to the theory postulated in this paper delivers a prescribed immittance response. A driving- point function F bar (s) is realized by a single-T circuit and/or a single-pi circuit, implying a negative resistor but otherwise positive elements; a positive real immittance function F(s) is realized by the same circuits augmented by an immittance kf(s) of low rank at the input. The circuit has high reliability and a rugged stability in the face of environmental changes. In addition, its low weight and small size fulfill requirements for military applications.

DOWNLOAD EBOOKThe design of networks having a prescribed driving-point impedance as a Brune one-port is well known and discussed in almost any textbook on linear and passive network synthesis. However, this classical design procedure is tedious, the more the degrees of the polynomials implied in the prescribed function increase. Besides that, numerical inaccuracies will be encountered. Also, this classical procedure can hardly be programmed for computer design. The modified version to be discussed in this paper yields explicit formulas by which all constants and polynomial coefficients of the requested circuit can be computed. Without any special effort, the results are extremely accurate. It is also shown that a Brune section has the property such that an inductance or a capacitance that appears as either a series or a shunt element at its input can, under certain conditions, be transposed over the section ti its output. This allows one to apply only one design program that covers all categories of driving-point functions which are realizable in the Brune fashion. (Author).

DOWNLOAD EBOOKIt is shown that a positive real immittance function F(s) is of one of eight categories. The category can be recognized by the sign polarities of three test values that are functions of the coefficients of F(s). If F(s) is of a certain category, then 1/F(s) can only be of some other categories. According to the categories of F(s) and 1/F(s) the immittance function can be realized (1) either by an RC or an RL network with positive elements, (2) by an RLC network with exclusively positive elements and an equivalent model circuit, or (3) only by model circuits. A model circuit is an RLC ladder structure with one negative branch element. The RC, RL, RLC, and model circuits have several equivalences.
