MEMS mics moving into mainstream Product News 9/22/2008 Post a comment Micro-electromechanical system (MEMS) microphones were once the darlings of startups, but no more. Analog Devices (Norwood, Mass.) has announced a major thrust into the fledgling MEMS microphone market, predicted by Yole Development (Lyon, France) to sell 800 million units by 2010. Analog Devices' entry into this potentially high-volume market follows Infineon Technologies' entry last year, though neither company has yet reported shipping production units.
Can Hollywood bring 3DTV home? Design How-To 9/22/2008 2 comments Momentum is building for stereoscopic 3-D television as the next big thing, but the path to 3DTV winds through forests of alternative file formats, compression schemes, display technologies and patents.
A new standard for surround sound Design How-To 9/22/2008 Post a comment Until recently, the implementation of surround sound for radio broadcast has faced considerable challenges. Compatibility issues, poor surround quality and the high bit rates required for surround transmission, among other factors, have conspired to put the brakes on the multichannel juggernaut, leaving analysts and professionals to wonder exactly when 5.1 radio might finally become a practical proposition.
Evolution and design Design How-To 9/22/2008 Post a comment Twenty years ago, when someone wanted real-time audio on a personal computer, it typically meant toggling bit 1 in I/O port 97 to generate a pulse waveform through the PC's small built-in annunciator speaker. Ten years ago, real-time audio on a PC typically meant buying a PCI-bus plug-in sound card. In the past decade, however, the vast majority of PCs have emerged from the shipping box ready to play with motherboard audio solutions based on the Audio Codec (AC) '97 specification and its success
Optimizing dynamic range of balanced audio inputs Design How-To 9/22/2008 Post a comment Balanced interfaces are ubiquitous in professional audio systems due to their ability to reject common-mode hum and noise. They are especially important in long-distance connections where each end has a different ground reference. Maximizing common-mode rejection (CMR) is often a primary concern of designers. This article explores another important consideration--maximizing dynamic range.
High-performance ICs learn to bend and stretch News & Analysis 9/22/2008 Post a comment IN ELECTRONICS, rigid and flat is normal. In the real world, not so much. There are many applications in which it would be useful for electronics to conform to curvilinear surfaces or to deform with use, especially in sensing. A detector array could be made to encircle the heart, stretching with each beat. An artificial skin could be stretched around the wing of an aircraft, relaying detailed local information while in flight. An artificial retina could fit in the curved space at the back of the
