Lowering ispPAC frequencies to the audio range News & Analysis 1/24/2002 Post a comment The ispPAC family of analogue components gives the circuit designer the flexibility of designing general-purpose analogue signal processing applications using in-system-programming (ISP). Designs are completed on the PAC Designer software and downloaded to the devices in milliseconds allowing the completed design to be immediately evaluated. Configuration data is stored in non-volatile memory enabling retention of circuit designs while power is turned off.

TI claims highest analog integration on MCU for embedded displays News & Analysis 1/22/2002 Post a comment DALLAS -- Texas Instruments Inc. today claimed it has broken the 1-microampere barrier in a low-power 16-bit microcontroller, which integrates mixed-signal functions and flash memory for embedded display applications in utility metering, portable instruments, intelligent sensing, and other systems.
Interface line topologies rule high-frequency applications News & Analysis 1/21/2002 Post a comment Engineers typically treat 3-inch-long traces as short interconnects, with few high-frequency considerations. But this approach often overlooks problems with interface operation or RF emissions, writes engineer Mike Grabois in this original contribution to Planet Analog. We need to recognize where various line topologies turn into transmission lines, he says.

A New Method for Clock Recovery in MPEG Decoders Design How-To 1/15/2002 Post a comment Using a Least Mean Squares technique, Hooman Hassanzadegan (Basamad Negar Company) and Nima Sarshar (Sharif University of Technology, Iran) describe a novel way to perform clock recovery in MPEG decoders. The technique also reduces the PLL hardware you need to do the recovery.
Conexant adds encoders for HDTV video on PCs, DVD, game systems News & Analysis 1/14/2002 Post a comment NEWPORT BEACH, Calif. -- Conexant Systems Inc. today announced an expansion of its broadcast video offering to include new encoders that cut the cost of "TV-out" solutions for displaying high-definition television (HDTV) on PC systems, DVD players, game consoles, and other new systems.
Pro Logic II matrix decoder melds multimedia News & Analysis 1/9/2002 Post a comment As more people have come to appreciate the benefits of surround-sound playback, they also want nonsurround program material-particularly music-to take full advantage of their multichannel playback systems. This desire is not only for home theaters, but also for car audio systems, computers and even headphone listening. The Dolby Pro Logic II 5.1-channel matrix decoder was designed with these expanded uses in mind.
Digital pots shrink volume controls News & Analysis 1/9/2002 Post a comment In this circuit-oriented piece, Maxim's application guru gives pointers for giving digital potentiometers the logarithmic taper found in mechanical volume controls - and ensure left-right channels are balanced to within a few dB.
Decimation Stages with WDFs for Flexible Digital Receivers Design How-To 1/9/2002 Post a comment Dieter Brckmann of the University of Wuppertal, Germany, describes a decimation filter architecture for highly optimized but flexible digital receivers. By using cascaded low-order wave digital filters for certain blocks, you reduce hardware cost and get superior sensitivity properties with respect to coefficient quantization effects, better noise performance, and less group-delay distortion.
California Micro sees order growth, but still expects loss in quarter News & Analysis 1/7/2002 Post a comment MILPITAS, Calif.--California Micro Devices Corp. today affirmed previous estimates of $7-to-$7.5 million in revenues in its fiscal third quarter, ended Dec. 31, and a pro-forma net loss of $0.38-to-$0.40 per share, before restructure charges and other items related to the company's new manufacturing model.

Overview News & Analysis 1/3/2002 Post a comment n home stereo, conventional wisdom suggests digital signal processing has taken over more and more of the audio signal-processing chain.
Drones are, in essence, flying autonomous vehicles. Pros & cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight, as are piloted airplanes? Is the technology advancing faster than we can answer the questions it poses?
