    Digital electronics at gigabit-per-second data rates is emerging as a new branch of science and engineering. A particular field of application opens up in advanced radar and sensing systems where large amounts of data have to be dealt with in real time. Analog-to-digital (A/D) converters with microwave sampling rates and multipliers for high-data-yield processing are specifically required subcircu... View full abstract»

    A comprehensive theoretical analysis of the development of passive mode-locking in a giant pulse laser is presented. After a review of previous work, a rate equation approach is used to obtain a simple mathematical condition defining the "second threshold" of the system, close to which the best mode-locking occurs. In addition, a computer model enables the influence on the mode-locking quality of ... View full abstract»

  • An alternative simultaneous maximally flat approximation for a low-pass recursive digital filter

    Cited by:  Papers (1)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (177 KB)  

    Digital filters with either maximally flat magnitude or maximally flat group delay are known [1]-[3]. This paper offers an approach to the design of a recursive digital filter with simultaneous approximation to both magnitude and phase. Although the same Taylor norm is used, this described technique is different from the previous approach [4] in the sense that it employs a power series expansion a... View full abstract»

  • The time domain solution of the Volterra functional equation: Application to nonlinear circuit analysis

    Publication Year: 1979 , Page(s): 431 - 432
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (180 KB)  

    An iterative technique to solve Volterra integral equations based on the Newton-Raphson method is presented which has a wide region of convergence, enabling the analysis of grossly nonlinear circuits. Instead of performing convolution in the frequency domain, the algorithm computes directly in the time domain which is found to be more efficient, if the number of time steps is maintained within a s...

    In this letter, the regression function for a BPNL network is computed. As a function of the input variable x(t) it can be expanded in a series involving Hermite polynomia. This property has far-reaching consequences for experimental determination of network parameters. View full abstract»

  • Assessing GaAs high-speed-switching JFET device models: 1- versus 2-dimensional analysis

    Publication Year: 1979 , Page(s): 435
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (168 KB)  

    The general results and conclusions of these researchers and others investigating 1- and 2-dimensional device models for high-speed low-power GaAs switching JFET's are briefly reviewed and summarized. Guidelines for assessing 1- or 2-dimensional device model adequacy based upon device geometries and dopings are proposed. View full abstract»

  • Current transport in large-area Schottky barrier diodes

    Publication Year: 1979 , Page(s): 436 - 437
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (246 KB)  

    The conventional method used to determine the mechanism of current transport in a Schottky barrier diode can lead to erroneous inferences if a fluctuation of parameters, such as that which would occur in a large area diode, is present. This has been illustrated by taking a Gaussian variation of a parameter in case of diodes showing T0anomaly. View full abstract»

  • Spectral estimation: An impossibility?

    Publication Year: 1979 , Page(s): 437 - 438
    Cited by:  Papers (2)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (223 KB)  

    Many methods of estimating the power spectrum are based upon the autocorrelation function. As the data is finite in duration, only a portion of the autocorrelation function can be directly estimated. An example of the insufficiency of using only a portion of the autocorrelation function for spectral estimation is discussed. View full abstract»

  • Figures of merit of windows for power density spectrum estimation with the DFT

    The figures of merit of windows for harmonic analysis proposed by Harris [1] are discussed, and other figures of merit are investigated. An interesting result is that for the estimation of the power density spectrum from a limited amount of data, the only relevant characteristic of a window is the spectral sidelobe level.

    A new class of nonlinear systems with explicit solutions is introduced. The importance of this new class of systems is pointed in terms of their significance in the reachable set computation problem for linear systems with polyhedral constraints on the initial state and prescribed control signals.

    The discrete phase lock loop (DPLL) proposed by G. S. Gill and S. C. Gupta [1] is simulated with a programmable calculator (TI-58). Many interesting properties of its behavior are easily shown such as the pulling-up time, the effects of varying the coefficients of the filter, and the effect of phase and frequency steps on the output. If the constant K1of the filter is initially made hig... View full abstract»

    A solar-electric system is proposed and discussed. This system uses concentrated mirrors focusing on a thermophotovoltaic (TPV) converter. Within the TPV converter the concentrated sunlight heats a refractory radiator. A silicon photovoltaic cell faces the radiator, receives incandescent radiation from it, and converts this radiation into electricity. View full abstract»
