This two-part article series reviews new developments in the Fourth Generation Long Term Evolution (4G-LTE) cellular standard. The series explores LTE-Advanced (LTE-A) Release-12 (Rel-12) features and ...

Analog transmitters have evolved from simple 4- to 20-mA current loops to designs that include µCs for signal conditioning at the transmitters and designs that allow bidirectional digital ...

DRM is the perfect radio solution to introduce digital radio services complementing the existing analogue services in all the broadcast bands (SW, MW, VHF band I, II and III). DRM allows radio ...

Machines need sensors and transmitters to operate reliably and consistently. All it takes is a small drop in air pressure or a slight jam to cause a machine to crash; these sorts of problems can often ...

A new silicon chip transceiver invented at UC Irvine is ultrafast and energy-efficient. The innovation relies on a unique mix of analog and digital technologies. It facilitates connected cities, ...

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a ...

Medical ultrasound imaging is a non-invasive method of viewing internal organs and structures of the human body using high-frequency acoustic waves. Sending an acoustic wave into the human body and ...
