    Existing large scale binary computers typically must allow for the maximum full length carry time in each addition. It has been shown that average carry sequences are significantly shorter than this maximum, on the average only five stages for a 40 digit addition. A method is described to realize the implied 8 to 1 time saving by deriving an actual ``carry completion'' signal. Experimental results verify this saving. View full abstract»

    An electro-optical binary storage device has been built which consists of a vacuum diode containing a photocathode and a phosphoranode. The device is capable of storing both optical and electrical information pulses. The present paper comprises a description of the behavior and construction of the prototype diode, an empirical derivation of a criterion for the conditions of stable feedback, and a numerical calculation for the case of two electrode pairs. Briefly mentioned are the possibility of high speed storage of digital information, the problem of self-triggering, the applicability of the criterion to solid state devices, and the analogous bistable behavior of a radio frequency triggered neon diode.

    Counter stages having three stable states, and using no more components than standard binary counters, have been built by properly using the already present nonlinearity of grid current. Problems of stability, cascading, and decoding have been worked out. View full abstract»

    This paper describes an analog to digital converter which converts voltage into a number which is proportional to the logarithm of the voltage. The device is completely automatic. It can handle input data at the rate of 10,000 voltage samples per second. The accuracy of conversion or quantization is determined by the designer's selection of the circuit parameters. The Radiation Laboratory quantizer has a maximum quantization error of 5 per cent. Samples of duration greater than .5 microsecond can be quantized. View full abstract»

  • High Density Williams Storage

    In this study, an investigation was made to discover methods of storing more bits on a Williams tube than can be stored by conventional methods. Read-around was ignored because the object was to explore the Williams tube as a secondary memory for non-random access operations. Proceeding on this basis, it was found that a four-fold increase in packing is possible with established techniques, and an even greater increase with other methods described in this paper. Such a memory is more versatile than a magnetic drum, as shown by the example of machine organization presented in this paper. View full abstract»
