    The measurements made on a system containing noise are usually time averages of the signals, or of quantities defined in terms of the signals. Such measurements are called time statistics. The object of this paper is to develop the theory of time statistics and in turn to give methods for calculating them. For the most part the time statistics are formulated in terms of ensemble statistics which a... View full abstract»

    An n-place binary parity check code which corrects up to and including e errors in each code letter is fully described by its n characteristics, which are r-dimensional vectors, where r is the number of redundant binits in each code letter. It is shown that the characteristics of such a code have the essential property that any subset of 2e of them are linearly independent. An upper bound on r for... View full abstract»

    This paper demonstrates the applicability of the functional equations of dynamic programming to information theory problems. Yielding the same results as those obtainable by Shannon's equations, the functional equations can be modified also to consider the many restrictions enforced upon information systems by the real world. A result of the application of functional equations to systems operating... View full abstract»

    The capacity of a certain asymmetrical binary channel is studied under the following conditions. 1) Blocks of equal numbers of binary digits are used as the transmitting symbols. 2) The channel resumes its quiescent state at the beginning of each block. 3) The memory of the channel is characterized by the dependence of the noise probabilities for each digit upon the preceding digit or digits in th...

    This paper considers the fourth product moment, w(τ1, τ2, τ3) = E[x(t)x(t + τ1)x(t + τ2)x(t + τ3)], when x(t) is infinitely clipped noise with a mean value of zero. If the noise is Gaussian before clipping, the moment w is not obtainable in closed form. For this r... View full abstract»

    It is shown that the envelope of a narrow-band Gaussian noise constitutes a first-order Markoff process if the power spectrum of the noise is the same as would be obtained from a singly tuned RLC filter with white noise at the input. View full abstract»

    This work generalizes the Wiener-Kolmogorov theory of optimum linear filtering and prediction of stationary random inputs. It is assumed here that signal and noise have passed through a random device before being available for filtering and prediction. A random device is a unit whose behavior depends on an unknown parameter for which an a priori probability distribution is given. A number of engin... View full abstract»

    In a recent paper,1 Barrett and Lampard introduced an expansion for second-order probability distributions which expresses such a distribution as a double series involving orthogonal polynomials associated with the corresponding first-order probability distributions. Several interesting consequences were derived for the class, A, consisting of all second-order distributions having a dia... View full abstract»

    The purpose of this note is to point out a simple but interesting result which is obtained when the ideas of Statistical Decision Theory1 are applied to estimate the parameters of signals represented by a linear expansion of orthogonal functions.2 View full abstract»

  • On Manasse, Price, and Lerner, ‘Loss of signal detectability in band-pass limiters’

    Manasse, Price, and Lerner have recently demonstrated1 the remarkable fact that it is possible to reduce the signal-detectability degradation factor of a band-pass limiter to unity by adding strong noise of low spectral intensity and sufficient bandwidth to its input. The purpose of this letter is to elucidate the phenomenon. View full abstract»
