  • Transient Response of Cascaded-Tuned Circuits

    Publication Year: 1954, Page(s):65 - 68

    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»

  • A Note on Filter Synthesis

    An equal-ripple type of approximation to constant attenuation in both stop and pass bands is often desirable in electric filter design. Elliptic functions have been extensively employed in solutions of problems of this sort. Double-entry tables are required and the mathematics is, in general, involved. This paper describes a design method that avoids the use of elliptic functions. A closed-form so... View full abstract»

  • Numerical Analysis for Network Design

    The numerical-analysis techniques appropriate for the rapid ap- proximate analysis of network response can be unified in terms of the z transform, or generalized Laplace transform. Application of the methods of analysis requires knowledge of only the z -domain integra- tion operators for the multiple integration of impulse trains. The time functions can be approximated by rectangular pulses, strai... View full abstract»

  • The Introduction of Constraints into Feedback System Designs

    Publication Year: 1954, Page(s):39 - 49
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1238 KB)

    Networks are frequently designed on the basis of minimizing a meas- ure of error to a given specification. The physical limitations of prac- tical circuit elements can often be introduced into such problems by means of constraints placed on the form of the solution. The paper presents_anew way of introducing such constraints and reviews some examples in which constraints have been successfully emp... View full abstract»

  • Transient synthesis in the time domain

    One of numerous available methods is described for synthesizing a network to have a specified transient response, with emphasis placed on the actual procedure of solution. This method, which is based upon the use of orthogonal exponential functions, is carried out prin- cipally by time-domain rather than the more common frequency- domain operations. It enjoys a broader applicability than most othe... View full abstract»

  • A General Method for Time Domain Network Synthesis

    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»

    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»
