    A basic circuit, consisting of a diode modulator controlled by the signal from a diode detector, may perform logical AND, EXCLUSIVE-OR and OR functions upon pulsed microwave signals. Pulse rates up to 500 mc have been used at a carrier frequency of 11,000 mc. To demonstrate that microwave circuits may be used for the regeneration and circulating storage of pulses, as well as for logic, a digital a... View full abstract»

    The properties of presently available components place special emphasis on two desiderata of logic design for use in a microwave digital computer: 1) Smallness of the number of active elements; 2) elimination of information-cycling paths having delay times comparable or short compared with the bit period, as in the conventional flip-flop. A logic design developed in response to these pressures is ... View full abstract»

    The ability of the Parametric Phase-Locked Oscillator (PLO) to detect, amplify, and store binary digital signals, in the form of two distinct phases of a carrier, makes it possible to use the device as the sole component in a digital computer system. The variable-capacitance version of the device operates readily at kilomegacycle frequencies, thus forming the basis of a digital computer at a kilom... View full abstract»

    The parametric subharmonic oscillator operates by energy transfer from the pump frequency to the oscillator frequency through a nonlinear energy storage element-in the present case, the nonlinear capacitance of a semiconductor diode. This paper examines both the requirements on the diode for satisfactory performance in this circuit and the limitations on oscillator performance which arise from the... View full abstract»

    In a carrier-type digital computer system, binary information can be represented by the presence or absence of an RF pulse in a given time interval. Using strip-line printed circuit techniques and point-contact diodes, passive AND and NOT gates were constructed which operate with RF pulses of less than 2 mμsec duration (i.e., an effective pulse repetition rate of 500 mc), at a carrier freq...

    It is possible to control the transmission of microwave power in a waveguide via external control of the dc bias on a semiconductor diode mounted across the waveguide in a direction parallel to the E field. The combination of a microwave detector with such a modulator affords a means whereby RF power in one waveguide can be made to control RF power in a second waveguide. In order to test the appli...

    A MATRIX representation which is particularly useful for the linear analysis of circuits with time-varying parameters will be given and will be applied to the case of a variable capacitance transmission line. The line will first be treated on the assumption that only a signal and a pump frequency (2ωsignal = ωpump) are important, and the conditions which should be satisfied by the ... View full abstract»

    The cold cathode counting tube, also called the decade glow transfer tube, is used principally in preset counter, timing and gating circuits. The number stored in the tube is often required to be recorded. This paper describes a technique whereby the content of the tube is recognized and read out through a carrier signal applied to the anode and 10 detectors connected to the 10 cathodes. The reado...

    The block diagram of an idealized over-all error-correcting digital computer is presented. This computer has the property that during each unit time interval, it can correct the effects of a specific maxium number of transient-type component failures which might occur anywhere within it. Yet, all its combinational logic circuitry is only of the error-detecting type. The corresponding reduction in ... View full abstract»

    The general class of sequential machines defined by Mealy is investigated. It is found that any such machine can be identified with a set of machines of equivalent minimality. A procedure for developing the aggregate of all sets of gates for such minimal machines is evolved, and the problem of selecting components for constructing machines is discussed.

    A technique is presented for reducing an arbitrary machine S as much as possible to a machine T which can do everything (from the input-output point of view) that S can do. Since the technique is always applicable, it is more powerful (although more cumbersome) than the well-known merging technique. Several examples are given. View full abstract»

    Given a sequential switching function in the form of a flow table in which some of the entries are unspecified, the problem of reducing the number of rows in that flow table is extremely complex, and cannot, in general, be solved by any simple extension of the methods used for completely specified functions. An analysis of the problem is presented, and a partially enumerative solution is evolved. ... View full abstract»
