    Linear discrete-time (sampled-data) filters can be implemented in monolithic form on an MOS chip using a variety of recently developed and newly emerging techniques without requiring analog-to-digital conversion. An analog signal sample can be represented by an isolated quantity of charge and such packets of charge can be stored, transferred, and manipulated in other ways to perform signal processing operations. Best known of these techniques is the use of a charge-coupled device (CCD) to operate as an analog shift register. A simple modification of the CCD shift register allows the realization of transversal filters. Other techniques can implement recursive filter operations offering a great flexibility for filter design. The possibilities and limitations of charge-transfer filtering are reviewed and examined.

  • Power system dynamic response calculations

    Engineers in the power industry, face the problem that, while stability is increasingly a limiting factor in secure system operation, the simulation of system dynamic response is grossly overburdening on present-day digital computing resources. Each individual response case involves the step-by-step numerical solution in the time domain of perhaps thousands of nonlinear differential-algebraic equations, at a cost of up to several thousand dollars. A high premium is thus to be placed on the use of the most efficient and reliable modern calculation techniques. This paper is a critical tutorial-review of the calculation methods used routinely or investigated for use by the industry. It concentrates on solution concepts and computational techniques rather than on the analysis of the numerical methods. Details of system modeling are only emphasized when they affect the choice of solution method. The paper concludes with a view of the state of the art and a prediction of future directions of development. View full abstract»

    This paper provides a review of the subject of electric power load management. In Section I, we briefly introduce the topic and then provide a summary of the current operating characteristics of electric energy production and delivery (EEPD) systems. Section II places load management in the context of the broader set of energy management strategies available to EEPD systems. The organization and rationale of the paper is then explained. In Section III, we review the set of communication/control technologies available or under development for use in the implementation of load management in EEPD systems. We provide an assessment of the relative attractiveness of alternative technologies, a brief summary description of a major field demonstration being jointly funded by EPRI and DOE, and two examples which illustrate the state of the art in modern two-way systems. In Section IV, we review the conventional approach to U.S. electric rate design, describe the current national Electric Utility Rate Design Study, review some important basic ideas of microeconomics, explore the subject of price elasticity of demand, examine the basic ideas underlying marginal cost pricing, discuss some of the practical difficulties of implementing time dependent rates, briefly examine some foreign rate design experience, and conclude by summarizing a number of U.S. rate design experiments sponsored by NSF and by FEA (now DOE). Section V is devoted to an examination of the problems of finding manageable loads in the residential, commercial, industrial, and transportation sectors. Particular attention is given to the development of thermal storage systems for water heating, space heating, and space cooling. Section VI is devoted to summarizing a number of studies which have attempted to assess the short- and long-term economic impacts of load management. The state of the field is such that few definitive cost/benefit statements can be made at this time. A number of potential social impacts are discussed and some broad regulatory policy guidelines are suggested. Finally, in Section VII, we highlight conclusions reached in the five preceeding sections, and identify a number of research and policy needs. View full abstract»

  • Least square collocation as applied to the analysis of strip transmission lines

    The crude method of collocation applied for the solution of the boundary-value problems has been improved upon in a least square sense for solving complex problems in applied mechanics. In this letter, the least square collocation method is applied for the solution of the electrostatic field problem of the strip transmission line enclosed in a shielded box, which is a case of mixed boundary-value problem. Compared to the other previous numerical methods, this method is much less laborious, simpler, and faster, and the results agree well with those available in the literature. View full abstract»

    It is shown how first-order polynomial correlation procedures can measure components of the regression function of a nonlinear network. The components can be determined independently if Hermite polynomials are used in the correlation procedure. View full abstract»

  • On inductor simulation: Reactive two-pole synthesis with all-pass and related transfers

    The paper looks at the synthetic inductor realization problem from the reactive two-pole approach which can be related to more esoteric gyrator norator models. It is shown that all that is required to realize a theoretically pure grounded inductor is a particular transfer function (related to the all-pass) which can be combined with a bootstrap configuration to obtain an active two-pole with a reactive input impedance. Circuit topologies are presented which can simulate an inductor. View full abstract»

  • A third-order active-filter realization having a complex pole with a low-Q sensitivity with respect to the gain-bandwidth product of operational amplifier

    A third-order state-variable filter realization using operational amplifliers is proposed to realize a high-Q high-frequency complex pole. This realization, under the optimal design condition, eliminates the effect of the gain-bandwidth product of the operational amplifier on the Q of the complex pole and ensures the stability. Hence high-Q high-frequency poles can be realized using this method. View full abstract»

    Two methods for compensating the well-known Deboo integrator are described. The first method is based on passive compensation and the second is based on active compensation. Both methods are equivalent and result in an improvement of many orders of magnitude in the integrator Q factor. View full abstract»

    A new configuration for activating a passive-RC bandpass building block to realize an inverting selective bandpass filter is described. The proposed network has the advantages of being canonic, is always stable, and has reduced sensitivity to the amplifier gain-bandwidth product. View full abstract»

  • Image detection in the presence of speckle

    Publication Year: 1979 , Page(s): 326 - 328

    Detection of binary images is considered in the presence of both speckle and additive noise. The detector performance has been evaluated in the presence of speckle as well as in the absence of it. It is observed that the presence of speckle increases the probability of error appreciably even at high signal-to-noise ratios (SNR's). View full abstract»

  • The latency reduction of bidirectional magnetic bubble memories

    Magnetic bubble memories have a significant advantage over rotating disk memories as they have no angular momentum. This characteristic theoretically allows them to remain in one position and then be started immediately in either direction. Presented are the results of a simulation of a simple magnetic bubble memory system, which demonstrate that an order of magnitude decrease in latency is possible by going to a bidirectional memory from a unidirectional memory.

    Based on dynamic strain, we derive analytically the fatigue damage criterion of ACSR conductors subject to aeolian vibration. This supports the laboratory and field findings of Rawlins that the damage criterion is independent of size and type of ACSR conductors and of tension. View full abstract»
