    A linear three-terminal deviceZis imbedded in a lossless passive network N and the properties of the complete system, as measured at two specified terminal pairs, are described by the open-circuit impedancesZ_{11}, Z_{12}, Z_{21},andZ_22. A search for properties ofZwhich are invariant under the transformation N leads to the quantityU = \frac{|Z_{21}... View full abstract»

    This paper presents one approach to the general problem of synthesis in the time domain. Given an arbitrary time function as the speci- fied input to an electrical network and another such time function as the desired output, it shows how to go about designing the net- work. These arbitrary time functions may be prescribed either graphically, analytically, or merely as sequences of values at state... View full abstract»

  • Simultaneous Oscillations in Oscillators

    An oscillator with two degrees of freedom can, under certain conditions, oscillate simultaneously at two different frequencies. The ratio of the two frequencies may be rational (synchronous oscillations) or irrational (asynchronous oscillations). The conditions necessary for 'simultaneous oscillations are discussed for these two cases. The problem is essentially non-linear and cannot be solved by ... View full abstract»

    Physical systems with very large number of variables (say with tens of thousands of variables) may be solved with already available digital computers by tearing the system apart into a large number of small subdivisions, solving each subdivision separately, afterward interconnecting the partial solutions by a set of transformations to obtain outright the exact solution of the original system, Amon...

    In the case of band-limited signals, the sampling theorem permits us to replace analytic operations with algebraic operations. We are then able to discuss problems of measurement of information, coding, and transmission over noisy channels in terms of discrete samples, rather than continuous time functions. The design of the optimum linear filter reduces from a very difficult analysis problem invo... View full abstract»

    The transient response of two cascaded stagger-tuned amplifier stages to a pulse of arbitrary carrier frequency is derived, starting from the response of a single-tuned circuit. The results are obtained by solving the differential equation of the network, and by employing a simple stratagem that immediately yields the arbitrary constants. The result is extended to three stagger-tuned stages, and t... View full abstract»

    The approximation problem of network synthesis is surveyed with extensive reference to the recent literature, encompassing both the frequency and the time domains. The topics reviewed include the concept of complex frequency, approximation by point-coincident polynomials, and the Fourier series method. Butterworth functions for maximally flat approximation and Tchebycheff polynomials for equal-rip... View full abstract»

    This paper presents a general mathematical technique for studying the response and stability of linear time-varTying circuits that contain parameters whose magnitudes vary in a periodic manner with the time, The method presented reduces the solution of the circuit differential equation to that of computing powers of matricesQ For purposes of illustration, the method is used to determine the respon...
