First Edition, First Printing (September 1978) of Joseph J. Carr's foundational work, "Digital Interfacing With An Analog World." Featured here is the highly desirable hardcover version (TAB Books No. 1070), which is significantly scarcer than the common later paperbacks.

Historical Significance: Released at the dawn of the personal computer revolution, this book served as the definitive "bridge" for engineers and hobbyists looking to connect early microcomputers to the physical world. It remains a prized reference for vintage tech restorers and "homebrew" computer builders today.

Technical Content:

• Transducers & Sensors: Detailed methods for measuring temperature, light, and pressure.

• Conversion Hardware: In-depth coverage of A/D and D/A converters, op-amps, and signal conditioning.

• Circuit Design: Includes over 270 logic diagrams and illustrations for interfacing with relays, motors, and triacs.

Condition Note: This well-preserved copy features a tight binding and clean internal pages. Minimal shelf wear is present on the hardcover boards. No significant highlights or marginalia were found.
