LRR- LINE REFLECT REFLECT is a new self-calibration procedure for the calibration of vector network analyzers (VNA). VNA measure the complex transmission and reflection characteristics of microwave devices. The analyzers have to be calibrated in order to eliminate systematic errors from the measurement results.

The LRR calibration circuits consist of partly unknown standards, where L symbolizes a line element and R represents a symmetrical reflection standard. The calibration circuits are all of equal mechanical length. The obs ....etc

The word mark, and its converse space, often appear in a description of a binary waveform. This is an historical reference to the mark and space of the telegraphist. In modern day digital terminology these have become HI and LO, or ‘1’ and ‘0’, as appropriate. ....etc

The accelerated growth of content-rich applications that demand high bandwidth has changed the nature of information networks. High-speed communication is now an ordinary requirement throughout business, government, academic, and work-at-home environments. High-speed Internet access, telecommuting, and remote LAN access are three services that network access providers clearly must offer. These rapidly growing applications are placing a new level of demand on the telephone infrastructure, in particular, the local loop portion of ....etc

The term On-Line Analytical Processing (OLAP) was coined by E.F. Codd in 1993 to refer to a type of application that allows a user to interactively analyze data. An OLAP system is often contrasted to an OLTP (On-Line Transaction Processing) system that focuses on processing transaction such as orders, invoices or general ledger transactions. Before the term OLAP was, coined, these systems were often referred to as Decision Support Systems.
OLAP is now acknowledged as a key technology for successful management in the 90's.It descr ....etc

The circuit presented here can beused for connecting two telephones in parallel and also as a2-line intercom.Usually a single telephone is connectedto a telephone line. If another telephoneis required at some distance, a parallelline is taken for connecting the othertelephone. In this simple parallel line operation,the main problem is loss of privacybesides interference from the otherphone. This problem is obviated in thecircuit presented here.Under normal condition, two telephones(telephone 1 and 2) can be usedas intercom while tel ....etc
