ABSTRACT
Wireless phones are increasingly being regarded as essential communications tools, dramatically impacting how people approach day-to-day personal and business communications. As new network infrastructures are implemented and competition between wireless carriers increases, digital wireless subscribers are becoming ever more critical of the service and voice quality they receive from network providers. A key technology to provide near-wireline voice quality across a wireless carrier's network is echo cancellation.

ABSTRACT
The term echo cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network.



Two sources of echo have primary relevance in telephony:
acoustic echo and
hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appe ....etc

Liquid Level Measurement Based on Ultrasonic Echo Characteristic
introduction
 Ultrasound is high frequency mechanical vibrations or pressure waves
 Uses sound waves(>20000Hz)
 Sound waves are transmitted as a series of compressions and rarefactions
 Wave propagation is longitudnal and mechanical displacement in same direction
About Ultra Sonic Technique
 Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as wel ....etc
