New MEMS Microphones for Mobile Phones, Portable Computers

 

STMicroelectronics’ two new digital MEMS microphones, MP34DB01 and MP45DT02, use acoustic sensor technology jointly developed with OMRON 2 that is less susceptible to mechanical vibration, temperature variations and electromagnetic interference, while providing high-fidelity reproduction of audio signals. These microphones incorporate multiple microphones in one device which … [Read more...]

Line Driver Demonstrates Compliance with EMI/EMC Requirements

 

Holt Integrated Circuits’ 5V ARINC 429 line driver, HI-8592, is compliant with the EMI/EMC requirements of RTCA/DO-160G, Section 21, Category P. Compliance with this specification ensures HI-8592 can operate successfully in applications mandating strict EMI/EMC requirements, such as cockpit instruments and flight controls. HI-8592 also meets the requirements of DO-160G, Level … [Read more...]

BBC Engineers See Power Line Networking Knocking out FM

 

Recent experiments carried out by the BBC demonstrate how Power-Line Networking can interfere with FM radio. Power-line networking, one of several ways to connect computers in a home, uses the electrical wiring in a house to create a network. The new study, commissioned by the BBC and authored by one current and one former BBC engineer, examines transmissions coming off … [Read more...]

'Magic Skin' Could Make Aircraft EMI- and Lightning-Proof

 

NASA has awarded Cessna Aircraft Co. a $1.9 million development contract for its self-healing “magic skin” for future aircraft. The idea is to pad the entire airliner with energy-absorbing foam, then slide the skin along the plane’s body. Once on, the snug-fit casing would protect the vehicle from impact damage, lightning strikes, electromagnetic interference and temperature … [Read more...]
