CAMAC based Test Signal Generator using Re-configurable device

Digital Test Signal Generator Implemented with FPGA

In this paper we present a digital generator which produces sine-wave signals with variable frequency. The shape of the signal is stored in memory. The modification of the frequency is achieved by changing the number of samples used to generate a period. The digital circuitry of the generator is implemented using a field programmable gate array (FPGA) and a microcontroller. Experimentally we ha...

A Configurable ACSL-Based Interface Generator for Simulated Systems

Design of a High-Precision DDS-Based Configurable Clock Generator

Configurable clock is necessary for many applications such as digital communication systems, however, using the conventional direct digital frequency synthesizer (DDS) as a pulse or clock generator may cause jitter problems. People usually employ phase-interpolation approaches to generate a pulse or clock with correct time intervals. This work proposes a new phase-interpolation DDS scheme, whic...

Re-configurable Terminals Beyond 3G

SUMTIME-MOUSAM: Configurable Marine Weather Forecast Generator

Numerical weather prediction (NWP) models produce time series data of basic weather parameters which human forecasters use as guidance while writing textual forecasts. Our studies of humans writing textual weather forecasts led us to build SUMTIME-MOUSAM, a text generator that produces textual marine weather forecasts for offshore oilrig applications. SUMTIME-MOUSAM separates control and proces...
