Editor's Notes

Dan Sheingold

In Volume 15­ 1 (1981), in celebration of 15 years in print, we listed the first 15 years of Analog Dialogue cover features. At that time, we wrote: “ . . . will mark the 15th year of publication of this journal, and the 13th year of our stewardship. While adding a copy of the [most recent] issue to our bulging binder, we nostalgically turned the pages of issues long forgotten. The amount of technological progress reported in them surprised even us. Before the list expands beyond the capacity of this column, we thought you might be interested in seeing a roll of just the cover stories alone, though much significant progress never attained the cover.” In this spirit, in celebration of our 30th year in print (and 28th of stewardship), here are the second 15 years of cover themes:

Howard Samuels is a Product Development Engineer in ADI’s Micromachined Products Division in Wilmington, MA. He joined Analog after graduating from Carnegie Mellon University in 1982 with a BS in EE and Applied Mathematics. He holds several patents and has published articles in trade magazines. Howard has designed signal conditioners and isolators, including the AD210 3­ port isolator. When not at work, he enjoys caring for and taking pictures of his new baby.

Matt Smith is a Senior Applications Engineer at our Limerick, Ireland, facility. He is responsible for Interface and Supervisory products. He holds a B.Eng from the University of Limerick. His leisure interests include playing squash, motor maintenance and more recently, woodworking.

Bill Slattery has marketing responsibility for products of the Digital Video Group at ADI’s Limerick facility, including video DACs, RAM­ DACs, and video encoders & decoders. Earlier, he worked as a Senior Engineer in the Applications Group in Limerick. Bill has a BSc (Eng) degree from the University of Dublin (Trinity College) and an MBA from the University of Limerick. A licensed private pilot, he enjoys flying his airplane.

Jürgen Kühnel is a Senior Marketing Engineer for Power Management products, located in Munich. Since joining ADI in 1984, he has had various roles in Sales and Marketing in Central Europe. His Dipl. Ing. is from the Technische Fachhochschule in Berlin, and he worked for several years as a system designer in medical and chemical instrumentation. In his spare time he likes riding on two wheels (powered or not) and designing electronic systems for his model railroad.

Dave Robertson is a design engineer in the Analog Devices High-Speed Converter group in Wilmington, MA. His photo and a brief biography appeared in Analog Dialogue 30-3.

Erik Barnes is an Applications Engineer for ADI’s High Speed Converter Group in Wilmington, MA. His photo and a brief biography appeared in Analog Dialogue 30-3.
