    The effect of delay line attenuation on the output of a correlator is studied for the case where the attenuation in db to within a frequency independent loss varies linearly with delay and as the square root of frequency. It is shown how attenuation affects the output signal-noise ratio of the correlator, increasing it for some signal spectrum shapes and decreasing it for others. Upper bounds on t...

    Expressions for the detection probabilities associated with the output of filter-square law detector-filter radar receivers are presented for practical filter systems and with a slowly varying Rayleigh distributed signal amplitude. View full abstract»

    This paper considers further how the decodability condition imposes restrictions on a set of code words. A generating function is defined that describes the composition of the code words. The relation between the generating function and a "full" set of code words is found. This relation shows that the sum of arbitrary probabilities associated with the words of a full set must be one. A full set of... View full abstract»

    Let Y(\omega ,\alpha ) be the Wiener filter designed to yield an output which is the least-square approximation to s(t + \alpha ) where s(t) is the desired signal input. Let Y_L(\omega ) be the Wiener filter designed to yield an output which is... View full abstract»

    A transistorized special purpose digital computer called MAUDE (Morse AUtomatic DEcoder) has been designed, built and analyzed. This computer decodes a hand-sent Morse message, which is printed on a teletypewriter. MAUDE's decisions take place at a number of different levels and its "knowledge" is not only that of relative durations of dots and dashes, but also of the Morse code and even of certai...

    A problem which arose during research involved in designing a machine to translate hand-keyed Morse code into printed text may be stated as follows: Let X = {x_i: i = l, 2, \cdots , n} be a sequence of independent random variables all of which have the same distribution. Assume that the probability that x_i = x_j , View full abstract»

    The so-called "pseudo-random" (p-r) sequences defined below have two properties which may make them useful in certain communication systems. Stated roughly, the first property is that the minimum distance between different signals of a special class is maximized and the second is that the probability that one member of this class be mistaken for some other member is minimized. The so-called "pseud... View full abstract»
