Precision Frequency Source...<br />
ULTRA STABLE OSC /LLAT411,<br />
BOOKS<br />
Modern Physics:<br />
A Textbook for Engineers<br />
Hycon Eastern's new Ultra Stable<br />
Oscillator is a one megacycle signal<br />
source of exceptional stability. It is<br />
useful wherever precise time measurements<br />
or frequency control are<br />
required, as in reinsertion of carrier<br />
in suppressed carrier systems, telemetry,<br />
astronomical measurements,<br />
navigation systems, geophysics or<br />
other critical applications.<br />
STABILITY: i PART IN 109<br />
FREQUENCY STABILITY: DRIFT RATE LESS THAN 1 PART IN 109<br />
PER DAY AFTER ONE MONTH'S OPERATION.<br />
FREQUENCY: I MEGACYCLE, VARIABLE OVER A RANGE OF I<br />
CYCLE. AVAILABLE AT OTHER FREQUENCIES ON SPECIAL ORDER.<br />
CRYSTAL OVEN: STABILIZED TO BETTER THAN 0.01°C BY TEMPER-<br />
ATURE- SENSITIVE RESISTANCE BRIDGE. OVEN CONTAINS NO MOV-<br />
ING PARTS.<br />
DISSIPATION IN OSCILLATOR CRYSTAL: STABILIZED AT A POWER<br />
LEVEL LESS THAN ONE MICRO WATT.<br />
2 OUTPUTS: SINE WAVE -4 VOLTS RMS; PULSE -1 VOLT.<br />
OUTPUT IMPEDANCE: APPROXIMATELY 250 OHMS.<br />

The need for nuclear- trained electronic<br />
engineers is so acute that the<br />
very title of this book should make<br />
it required reading for every well -informed<br />
engineer in the industry.<br />
The author, who is assoc. professor<br />
of physics at Cornell Univ., developed<br />
this book from notes used in a course<br />
for engineering undergraduates at<br />
Cornell, and in courses for practicing<br />
engineers at Westinghouse, Corning<br />
Glass and Sylvania. The approach is<br />
analytical, with emphasis on crucial<br />
experiments, and the elementary theory<br />
underlying the properties of<br />
atoms, molecules, solids, and nuclei<br />
is based on this analysis.<br />
Each of the chapters opens with a<br />
clear -cut and fundamental discussion<br />
of the material to follow. Mks units<br />
are used throughout.<br />
Chapter headings include: fundamental<br />
particles, assemblies of particles,<br />
atoms and nuclei, wave -particle<br />
experiments, introductory quantum<br />
mechanics, atomic structure and spectra,<br />
molecules, binding and energy<br />
bands in solids, semiconductors, physical<br />
electronics, and applied nuclear<br />
physics.<br />
The sections on solid -state physics<br />
and semiconductors will be invaluable<br />
to electronics engineers.<br />
Electronic and Radio<br />
Engineering<br />
By Frederick E. Termon. Published 1955 by<br />
McGraw -Hill Book Co., Inc., 330 West 42nd St.,<br />
New York 36, N. Y. Hard cover. 1078 pages.<br />
Price $12.50.<br />
The new title on this fourth edition<br />
of Terman's "Radio Engineering"<br />
reflects the increased emphasis on the<br />
general techniques of electronics. The<br />
book is divided into 3 parts. The first<br />
deals with transmission lines, and the<br />
basic circuit theory peculiar to electronics;<br />
the second, with electronic<br />
engineering - electronic devices and<br />
their applications; and the third, with<br />
radio engineering.<br />
Many additions have been made to<br />
the text, among them a chapter on<br />
microwaves, presenting an explanation<br />
of how the backward -wave oscillator<br />
(carcinotron) and the traveling<br />
-wave tube operate, as well as a<br />
chapter on transistors and semiconductors.<br />
The material on nonlinear<br />
waveforms and pulse techniques has<br />
been expanded, and the chapter on<br />
TV thoroughly revised. Increased attention<br />
is also placed on propagation<br />
involving the troposphere.<br />
