Partitioning and Design for Precision Data Acquisition Systems
Acquired analog signals can be manipulated and processed by either the
analog or digital portions of a system, for example, through filtering,
multiplexing, and gain control. The analog portions of a system can
typically provide reasonably simple processing at fairly low cost,
power, and overhead. Digital processing can provide far greater analysis
power and can alter the nature of the analysis without changing
hardware. Sampling theory, however, must be taken into account. This
session covers the signal chain basics from signal to sensor to
amplifier to converter to digital processor and back out again. This
session will focus on precision measurements; a later session will cover
dynamic and higher speed signal processing.
Dave designed medical electronic equipment before joining Analog Devices
in 1972 as an IC designer. Over the years, he has been involved in
analog chip design, wafer fabrication engineering, and new product
development and management. Dave has been instrumental in bringing to
market many new products and platforms focused on innovation and
enabling new application areas. For many years, Dave led ADI’s technical
support team. He earned both his BSEE and MSEE from Massachusetts
Institute of Technology.
