    The problem that is solved in this paper can be formulated as: given an observation of an image against the background of additive noise and given the statistics of the image and the noise, find an optimal estimate of the image such that the computer-time and storage requirements of the estimator are modest for images of, say 250 \times 250 points or more.

    For the prediction of manufacturing yield, a modeling technique based on the regionalization of a variable component space is combined with the computational technique of systematic exploration to provide, for linear circuits, a remarkably efficient prediction of the spread in circuit performance due to spread in a number of components. Illustrative examples enable the new approach to be compared ... View full abstract»

    The crucial role played by the man-computer dialogue in computer-aided circuit design, and particularly within an interactive graphic medium, is demonstrated by reference to a working circuit design facility implemented on a minicomputer. The detailed nature of this facility and the techniques illustrated are related to the circuit design process and the behavioral characteristics of the human des... View full abstract»

    The compression of voltage pulses by a cascade of transmission lines is investigated, and a simple derivation is given for the case in which the characteristic impedances of the individual lines are independent of the compression factor. The possibility of using a single nonuniform transmission line (NUTL) for voltage compression is examined, and it is shown that a distortionless compression is no... View full abstract»

    In Part I of this paper, a procedure for the synthesis of doubly terminated two-pair networks is developed. This procedure, coupled with certain properties of mirror and anti-mirror image polynomials, permits the design of digital filters with extremely low sensitivity of the steady-state magnitude of the transfer function to multiplier coefficient errors. In Part II, the ladder structure is exami... View full abstract»
