Time-Domain Measurement System to Characterize Ultrawideband Emissions

October 21, 2001
Author(s)
Robert T. Johnk, David R. Novotny
This paper summarizes some results of a recent NIST measurement effort. The purpose of this effort was to use a NSIT-developed ultrawideband measurement system to assess the time and frequency-domain characteristics of selected ultrawideband transmitting

Alignment of Noisy Signals

February 1, 2001
Author(s)
Kevin J. Coakley, Paul D. Hale
We study the relative performance of various methods for aligning noisy one dimensional signals. In each method, we estimate the relative shifts of a set of signals which are translated with respect to each other. We simulate signals corrupted by both

Artificial Neural Network Modeling for Improved On-Wafer OSLT Calibration Standards

September 1, 2000
Author(s)
Jeffrey Jargon, Kuldip Gupta, Donald C. DeGroot
We apply artificial neural networks (ANNs) to improve the modeling of on-wafer open-short-load-thru (OSLT) standards used for calibrating vector network analyzers. The ANNs are trained with measurement data obtained from a benchmark multiline thru-reflect

Security for Private Branch Exchange Systems

August 1, 2000
Author(s)
David R. Kuhn
This document provides an introduction to security for private branch exchange systems (PBXs). The primary audience is agency system administrators and others responsible for the installation and operation of PBX systems. Major threat classes are explained

Telecommunications Security Guidelines for Telecommunications Management Network

October 2, 1995
Author(s)
John Kimmins, Charles Dinkel, Dale Walters
This Telecommunication Security Guideline is intended to provide a security baseline for Network Elements (NEs) and Mediation Devices (MDs) that is based on commercial security needs. In addition, some National Security and Emergency Preparedness (NS/EP)
