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

ABSTRACT
The Line-Reflect-Reflect (LRR) technique is a new self-calibration procedure for the calibration of vector network analyzers (VNA), which are used for complex scattering parameter measurements of microwave devices.

The calibration circuits of LRR method 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. This is advantageous because the complexity of test fixture can be reduced. T ....etc

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.

ABSTRACT
Voltage sags, transients, and momentary interruption of power together constitute 92% of the PQ problems encountered by typical industrial customers.
Productivity loss due to deep voltage sags and brief power interruptions has
been called the most important concern affecting most industrial and commercial
customers. These power quality (PQ) events typically last for less than one second,
impressing voltage sags down to 50% of nominal voltage, with occasional short-term interruptions lasting for approximately ....etc
