A schemata model of real-time information processing systems

Creator:: Szulewski, Paul A.
Abstract:: In an attempt to provide a practical means to measure the information processing capacity of a real-time digital processing system a theoretical framework, the Real-Time Schemata, whose basis is a schematic description and a measure of "useful information," is presented. The description applies to processes that would typically be implemented...

Computer analysis of a class of acoustic signals

Creator:: Miller, Michael Robert
Abstract:: A procedure for displaying cursory computer analyses of time series acoustic signals is described. The graphic presentation is optimized for visual analysis. The results displayed represent time series signals and/or Power Spectral Density estimates. Both hardware and software components of the procedure are described and compared with current methods. Suggestions...

Multi-bit delta-sigma switched-capacitor DACs employing element-mismatch-shaping

Creator:: Lin, Haiqing
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters (ADCs and DACs). Most delta-sigma modulators in production today employ single-bit quantization because a 1-bit DAC is inherently linear, whereas a multi-bit DAC is not. Were it not for this drawback, the use of multi-bit...

Improving a sampled-data circuit simulator for Delta-Sigma modulator design

Creator:: Hayward, Roger D.
Abstract:: Delta-Sigma Modulator-based Analog-to-Digital converter design is an active area of research. New topologies require extensive simulations to verify their performance. A series of improvements were made to an existing circuit simulation package in order to speed the simulation process for the designer. Various examples of these improvements are presented in...

Delta-sigma modulators employing continuous-time circuits and mismatch-shaped DACs

Creator:: Zhang, Bo
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters. These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold. Though the initial...
