1. Multimoding and its Suppression in Twisted Ring Counters

Abstract

Many digital systems, such as PCM systems, data processing and data transmission systems, use twisted ring counters. Most of these twisted ring counters are subject to multimoding. This paper develops tools and methods for predicting all possible modes in twisted ring counters, and derives a general solution for suppressing the wrong modes. Suppression is accomplished by adding a few circuit connections from the output of certain stages to the input of another stage. The paper derives the number of necessary connection lines and their connection points for the various types of counters.

Abstract

Two laboratory computers have been interconnected through an addressed-block data transmission system (ring) as described by J. R. Pierce and implemented by W. J. Kropfl. This paper gives an idea of the equipment, programming, and protocols of communication through that system.

Abstract

This paper describes methods for the reduction of jitter in transmission chains with regenerative repeaters. These methods are based on the application of pattern transformations to the output signals of successive repeaters. As a result, the coherent accumulation of jitter from signal dependent jitter sources is prevented. Instead, the jitter accumulates on a power basis. It is shown that in this way a significant reduction of jitter is obtained. This result is demonstrated by both theoretical data and measurements on an experimental transmission chain which correspond fairly closely. Furthermore, the realization of the pattern transformations by simple coding techniques is presented in detail.

Abstract

This paper deals with two aspects of the investigations of mobile data transmission. The first aspect shows the equipment for measuring and recording of parameters that influence the transmission. The second aspect shows the development of an analog simulation of the data transmission with the possibility of adjusting significant parameters independently. Finally the applicability of the model is verified by comparison between simulation and actual transmission.
