A Case For Including Harmonic Distortion Components In Docsis’ Rf Specifications For Non Aggregating Spurious Components, Ron D. Katznelson Apr 2004

A Case For Including Harmonic Distortion Components In Docsis’ Rf Specifications For Non Aggregating Spurious Components, Ron D. Katznelson

Ron D. Katznelson

This note is submitted in support of a change in DOCSIS specifications for spurious performance. It shows that the impact of a proposed change is negligible and that the advantages far outweigh the perceived disadvantages of adopting such a change.

Specifying And Measuring Aggregate Broadband Noise Of Catv Modulators And Upconverters, Steven I. Rubin, Andre Basovich, Brani Petrovic, Ron D. Katznelson Jun 2002

Specifying And Measuring Aggregate Broadband Noise Of Catv Modulators And Upconverters, Steven I. Rubin, Andre Basovich, Brani Petrovic, Ron D. Katznelson

Ron D. Katznelson

This paper discusses the practical limitations and the subtle assumptions that must be incorporated into the specifications and measurements of Aggregate Broadband Noise of CATV upconverters and digital QAM transmitters. Considerations that govern the accuracy and measurement dynamic range required for such Aggregate Broadband Noise measures are identified. Novel methods involving the separation of the Aggregate Broadband Noise measure into its composites, namely, modulated distortion noise components and other broadband noise components are discussed. Optimal ways in which such measurement techniques have been automated to enable rapid and efficient evaluation of transmitter devices are also presented along with examples of …


Statistical Properties Of Composite Distortions In Hfc Systems And Their Effects On Digital Channels, Ron D. Katznelson May 2002

Statistical Properties Of Composite Distortions In Hfc Systems And Their Effects On Digital Channels, Ron D. Katznelson

Ron D. Katznelson

The statistical properties of Composite Triple Beat (CTB) and Composite Second Order (CSO) distortion terms associated with the analog channels carried on Hybrid Fiber Coax (HFC) are presented. Both simulation and measurement results show that such distortion components falling on individual channels have amplitude Probability Density Function that is nearly Rayleigh distributed (having a Standard Deviation of 5.7 dB). It is shown that both CTB and CSO components have peak envelope power fluctuations that exceed their average (measured) power levels by more than 15 dB. The temporal statistical properties of these distortion components demonstrate peak envelope power fluctuations with characteristic …


Reflexive Autopoietic Dissipative Special Systems Theory, Kent D. Palmer Jan 2000

Reflexive Autopoietic Dissipative Special Systems Theory, Kent D. Palmer

Kent D. Palmer

A newly discovered approach to extending General Systems Theory as defined by George Klir through a set of Special Systems is described. General Systems Theory is distinguished from the theory of Meta-systems. Then, a hinge of three special systems is identified between systems and meta-systems. These special systems are defined by algebraic analogies. Anomalous physical phenomena are specified that exemplify the structures defined by the algebraic analogies. The extraordinary efficacious properties of these special systems are explained. These include ultra-efficiency and ultra-effectiveness. These three special systems are called dissipative, autopoietic, and reflexive. They are anomalous within general systems theory and …


Results Of A Delphi Study On Transport Research Needs, Marcus Ramsay Wigan Jul 1995

Results Of A Delphi Study On Transport Research Needs, Marcus Ramsay Wigan

Marcus R Wigan

A Delphi survey was undertaken with a selection of professionals in academic, government and consulting across the world. The objective was to identify the application areas where priorities should be placed, and the current status of the research and information tools needed to address them. For this reason both modelling and application experts were included. The shifts in priorities over the last five years, and the differences in view between the three sectors are presented. The attitudes towards a range of specific research and development directions were also assessed. Later republished in the Journal of Transport Statistics, but without this, …
