COMPUTERS SELF
-TAUGHT THROUGH
EXPERIMENTS
by
Jack Brayton
It is
the author's
contention that
digital
com-
puters
are simple
rather than complex instru-
ments, and he
has written
this
book to
prove
it. He points
out that computers
seem
com-
plex because of their size, but that they
are
actually
made up of many simple circuits re-
peated thousands
of times. In
these
pages
discussions
of computer theory appear side
by side with details
that
enable
the reader to
construct
working models of the circuits -
which seems to us
an
excellent way
to
master
the subject.
All parts values, voltages, and
other circuit details are given,
and the parts
used
in
the
various experiments are both
readily
available and low in cost.

HANDBOOK
Richard
F. Shea, Editor -in -Chief
Truly
a giant of a volume (1516
pages,
410 il-
lustrations), this
handbook
provides
invalu-
able
reference material of
both a general and
a
specialized
nature. Prepared by a team of
outstanding authorities in
the
field, the book
is
divided
into
three
sections:
amplifier funda-
mentals;
devices;
and
circuits. All major
forms of amplifying
devices
(from
tubes and
transistors to
masers
and
lasers)
are de-
scribed, but
the
bulk of the book is devoted to
specific categories
of
circuits
and
includes
de-
signs ranging
from
one end of the
frequency
and power
spectra to the other. Wherever
possible, a design
is generalized
and the
necessary
information
provided to
develop
desired variations.
Emphasis
throughout is
on practical
applications.

A TOWER IN BABEL
by Erik
Barnouw
If you can
forgive the
minor technical errors
(the
author
has little knowledge of
elec-
tronics),
you should
find
this early
history of
broadcasting
fascinating reading. The
first
of
three
volumes,
it tells how broadcasting
started
and
is
spiced with anecdotes about
the
men and
women who foresaw a bright
future
for
radio.
