Cover Story
Fuzzy-logic design tools help build embedded systems	Fuzzy logic is slowly catching on, and fuzzy design tools are getting better: They don't just help design fuzzy logic, they let you create complete embedded systems. —Gary Legg, Senior Technical Editor
Design Features The hottest new technologies and the latest design techniques to help you work efficiently and effectively.
Asynchronous conversion thwarts incompatibility in sampling A/D systems	By using asynchronous sample-rate conversion, you can eliminate the problem of repeated or dropped signals that can occur when interconnecting systems with incompatible clock rates. —Robert Adams, Analog Devices Inc
Electromagnetic theory imposes constraints on pc-board design	An understanding of electromagnetic effects often leads to a better pc-board design than prototyping and debugging in the lab using traditional rules of thumb. —Gregory S Seltzer, Mentor Graphics Corp, and Reza Ahy and Monica Razmi, Stanford-Berkeley Associates
Analog HDLs advance speed and enhance modeling flexibility	Analog HDLs have been commercially available for years, but their acceptance in mainstream analog and mixed-signal design may coincide with an industry-standard language—or two. —Doug Conner, Technical Editor
