A data acquisition system (DAS) converts analog signals to digital for analysis by a digital signal processor. Applications such as imaging, audio, and vibration analysis require a DAS with a high signal-to-noise ratio (SNR) and ultra-low THD (total harmonic distortion). Developing a wi...
Digital X-ray (DXR), magnetic resonance imaging (MRI), and other medical devices require small, high-performance, low-power data-acquisition systems to meet the demands of doctors, patients, and manufacturers in a competitive marketplace. This article showcases a high-precision, low-power signal...
Today's digital controls are predominately referred to as Supervisory Control And Data Acquisition (SCADA) systems. Early pneumatic and analog control systems were isolated from organizations’ business systems. Simply putting the integration of process control data into the business decision-making ...
4.1.3General picture archiving and communication system design: introduction and impact A PACS consists of image and data acquisition, storage, and display subsystems integrated by digital networks andapplication software. PACS design should emphasize system connectivity and integration. A general multimedia...
1. A CT scanner comprising a source of X-rays, an array of detectors for detecting X-rays emitted by said source and received by said detectors, and a data acquisition system for processing signals generated by said detectors, said data acquisition system comprising a plurality of oversampling...
TheTMP03is a complete temperature data-acquisition system on a monolithic silicon chip. Including a silicon-based sensor, internal voltage reference, and sigma-delta A/D converter, it fits in a 3-pin (power, common, and output) TO-92 transistor package. Its digital output is a low-frequency...
Application Report SBAA094 – June 2003 Combining the ADS1202 with an FPGA Digital Filter for Current Measurement in Motor Control Applications Miroslav Oljaca, Tom Hendrick Data Acquisition Products ABSTRACT The ADS1202 is a precision, 80dB dynamic range, delta-sigma (∆Σ) modulator operating ...
Simplified dataflow diagram for the data acquisition system. The direct memory access (DMA) allows one to send the data directly to memory space for the CPU to process. Python scripts then record, process, or control the PDC via the kernel driver. As the ARM CPU has access to all resources...
The control block also monitors the device power consumption for USB compliance. The USB Controller interfaces with the PC for programming the volatile FPGA memory after power on or when a new configuration is requested. After that, it performs the data transfer between the PC and FPGA. The ...
A thorough understanding of data acquisition system is necessary in applying this module. The chapter also explores the fact that once the data values are acquired they are always needed for further processing—including offsetting, code conversion, and scaling. The chapter even provides information ...
