Multichannel Data Acquisition Systems



Precision Analog Applications Seminar

Multiplexing allows one ADC to do the work of several in a multichannel system. Rather than dedicating an ADC to each channel, a single converter can read every channel in sequence. This can save power, since ADCs can use a significant amount of power while switches use very little, and it can save cost, since switches are much cheaper than ADCs.

Implementation of Multichannel Sensors for Remote Biomedical Measurements in a Microsystems Format
Abstract
A novel microelectronic pill has been developed
for in situ studies of the gastro-intestinal tract, combining microsensors
and integrated circuits with system-level integration
technology. The measurement parameters include real-time
remote recording of temperature, pH, conductivity, and dissolved
oxygen. The unit comprises an outer biocompatible capsule
encasing four microsensors, a control chip, a discrete compon ....etc

Abstract Topology engineering concerns with the problem of automatic determination of physical layer parameters to form a network with desired properties. In this paper, we investigate the joint power control, channel assignment, and radio interface selection for robust provisioning of page link bandwidth in infrastructure multiradio multichannel wireless networks in presence of channel variability and external interference. To characterize the logical relationship between spatial contention constraints and transmit power, we formulate the joi ....etc

Abstract

Necessity of data acquisition system in instrumentation: -

- All engineering activities require collection of data, in development, production, quality control, management, process control etc.
- We have been using thermometer, voltmeters, scales, oscilloscopes and such variety of measuring devices and instruments to read the physical data.
- The emphasis is therefore on getting the machines to meet most of our data acquisition and control needs.
- Data acquisition is collecting data or information that describes the gi ....etc
