Electronic Clocks And Watches by Michael S. Robbins 1975

Hi All
Preface
The technology of timekeeping has changed dramatically in
recent years due, in part, to the development of microelectronic
circuitry. Digital electronic wristwatches would have been the
size of refrigerators in the early 1950s, and the size of cigar
boxes in the late 1960s. This book presents a brief history of
timekeeping and some fundamentals of various mechanical,
electrical, electronic, and atomic timekeepers.
The basic principles of digital logic and its application to
electronic timekeeping circuits are explored. The different
families of digital logic circuits and readout devices used in
clocks and watches are described.
Chapter 6 compares the characteristics and applications of
many popular LSI clock and watch circuits and presents some
circuit hints. Chapters 7 and 8 describe commercially available
electronic time-keepers. The detailed examination of some of
these products will give the electronics experimenter, the clock
enthusiast, and the engineer a better grasp of the circuits and
techniques used.
Chapter 9 presents two construction projects for the
do-it-your-selfers. Both have been tested extensively and will
work if the instructions are followed.
The two appendices contain data on some of the ICs and
readouts mentioned in the text and the names and addresses of
sources of components and kits.
The brief bibliography will open up a vast store of knowledge
to those interested in pursuing the fascinating avenues of
timekeeping.
Very much of book of the 1970' state-of-the art.

the book, cleaning the images and creating the PDF. My "work" was about
10 seconds copying it to my dropbox.
