Converter Short for digital-to-analog converter. This is a device that
changes a digitally coded word into its equivalent quantized analog
voltage or current. Just like the A/D device, there are very high-speed
D/A's available, capable of converting at data rates up to 1 GHz.
A completely automated factory floor with no labour.
all information of computer operations directed by the detailed instructions of the program.
|Data acquisition system||
any instrument or computer that acquires data from sensors via
amplifiers, multiplexers, and any necessary analog to digital
the act of bringing data from remote points to a central location, and its organization into understandable information.
A single, atomic piece of data that cannot be subdivided and still retain any meaning. The terms "data item" and "field" are often used synonymously with data element.
The process by which the reliability, timeliness and accessibility of an organization??s data base is assured.
where data reside.
A database for query and analysis, as opposed to a database for processing transactions. Separating the two functions improves flexibility and performance.
a collection of structured information.
20 times the log to the base 10 of the ratio of two voltages. Every 20 dBs correspond to a voltage ratio of 10, every 10 dBs to a voltage ratio of 3.162. For instance, a CMR of 120 dB provides voltage noise rejection of 1,000,000/1. An NMR of 70 dB provides voltage noise rejection of 3,162/1.
Database Management Systems access data stored in a database and
present multiple data views to end users and application programmers.
Direct current; an electric current flowing in one direction only and substantially constant in value.
Distributed Control System is a real-time control system for continuous and batch process applications.
