The Dependence Of Measured Modulation Error Ratio On Phase Noise, Ron D. Katznelson Aug 2008

The Dependence Of Measured Modulation Error Ratio On Phase Noise, Ron D. Katznelson

Ron D. Katznelson

This paper reviews the algorithms used by Vector Signal Analyzers to measure Modulation Error Ratio (MER) and derives the explicit functional dependence of measured MER on phase noise of digital transmitters. The modulation error model is introduced and the analytical expression for key estimated parameters required to obtain MER measure are derived. The essential elements of algorithms employed by MER measurement instruments to estimate amplitude scale, frequency offset, and initial phase intercept and the resulting MER are identified. The frequency response of the effective phase-noise rejection filtering action associated with a given measurement epoch is derived. It is shown that …


Bad Science In Search Of “Bad” Patents, Ron D. Katznelson Aug 2007

Bad Science In Search Of “Bad” Patents, Ron D. Katznelson

Ron D. Katznelson

This paper draws attention to fundamental deficiencies in studies that have been relied upon as authoritative sources on patent grant rate comparisons among national patent offices. The two prominent studies analyzed here had employed erroneous methods to compare patent grant rates, resulting in false high indications of such rates at the U.S. patent office compared to foreign patent offices. The three identified categories of analysis errors found in these studies were (i) the misapplication of conditional probability; (ii) miscounting invention applications; and (iii) failure to account for patent obsolescence and application attrition due to the widely differing delays among national …


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 …
