OLLBERG'S 'YOU AND TV':
Mysteries of Television Answered in Recent Booldet

By ALLAN STILLWAGON
Do you know how the picture is
formed on your television set?
or how a television camera
works?
Or why TV studios usually have
thousands of vacuum tubes?
These and a number of other
common questions about the mys-
tery of television are answered for
the layman in a new booklet,
"You and TV, by Robert Stoll-
berg, president of the National
Science Teacher's Association.
After a short, basic explanation
of the fundamentals of electricity,
Stollberg plunges into a lucid ex-
planation of picture tubes. Estab-
lishing that the picture tube is a.
specialized vacuum tube, he illus-
trates the fundamental operations
of its components. The electrons
in a picture tube are "shot" from
an electron gun at the back. The
cathode, heated by a powerful
electric heater, is the source of a
stream which is guided by deflec-
tion coils back and forth, up and
down the surface of the tube's
face.
A special deice called a control
grid controls the strength of the'
electron-beam and therefore the
brilliance of the picture. The min-
ute and temporary glow caused by
tiny bombardments on the sur-
face, multiplied by the thousands,
makes up the final image.
Studio Tour
Next, the reader is taken on a
* tour of a typical television studio,
into the heart of a television cam-
era. The camera, a complex elab-
oration of an ordinary Kodak, and
an electric eye, uses a process sim-
ilar in part to that in the home
receiver. An image of the per-
formers is formed by a lens on a
plate consisting of thousands of
tiny electric eyes. When light falls
on the eyes they produce an elec-
trial charge proportional to the
strength of the light. This series
of charges forms the video signal,
which is amplified and broadcast
from the TV transmitter.
In order that the reader might
understand the process by which
sight and sound are sent from the
studio to the home, radio waves
are reviewed next. Illustrations
tell the story of amplitude modu-
lation (AM) and frequency modu-
lation (fm). The line-of-sight path
of very high frequency waves, used
by both television and FM broad-
asting makes the construction of
coaxial cables and microwave relay
stations necessary.
Having a pretty good idea of
what happens in the TV station
and how a picture is actually
formed on a picture tube, the scene
shifts to the other fundamental
parts of the set.
Set Fundamentals
Starting at the antenna, which
is "aimed' for two sections of the
channel lineup (the large dipole
for lower channels 2 through 6,
and the smaller for higher han-
nels 7 through 13) travels down
twin-lead lead wires, to the re-
ceiver. Here, the fundamental steps
in the operation of a simple radio
circuit are reviewed. The steps
usually take' place in this order.
1. The radio signal from the
antenna is tuned, ,selecting the
signal desired, and "throwing-out"
the extras.
2. The selected signal is am-.
pified-
3. The stronger signal is chang-
ed into an electrical signal similar
to the one produced when the
sound struck the microphone at
the studio. This step is usually
called detection or de-modulation.
4. This detected signal is am-
plified some more.

5. The amplified electrical signal
is changed into sound.
These same five basic steps occur
in both the audio and video por-
tions of the home receiver, with
the exceptions that many addi-
tional substeps are included in the
vastly more complex circuits of
television. Step five additionally
changes electrical signals into both
sight and sound.
A look into the future is at-
tempted. It is hard to predict what
will or will not be true about
television five years or even five
months from ndw, but some de-
velopments are almost sure to
make an appearance.
New T. V. Uses
Non-commercial television, now
in extensive use throughout the
world, provides an ever-increasing
field of application. Television in
the operating room, in. both black
and white and color has proved
its value long ago. Military televi-
sion not only provides command-
ers on the ground a "bird's-eye-
view" of battle conditions, but
enables ground bound pilots of
guided missils to see a clear pic-
ture of the conditions ahead of
his ship. In general, closed circuit

ing to pay for movies or super-
spectacular productions in the
home.
Finally, ultra - high - frequency
and color television loom in the
horizon. UHF channels, the range
of which extends from 300 to 3,000
million cycles per second are now
being assigned to those cities with
no other TV facilities. In other
areas, battles rage over allocation
of the 12 VHF channels which all
sets in the country receive without
addition of special attachments or
converters.
Color Television
Although color sets remain in
the luxury class, dealers all over
the country report heavy sales of
this revolutionary new form of en-
tertainment. Daily program sche-
dules indicate a relatively high
percentage of color shows being
broadcast both nationally and lo-
cally. Color television may never ;
replace black and white, but it is
sure to ,be common within a very3

short time. fundamental understanding of its
Whatever the future of televi- secrets is a must for those who
sion, many surprises lie in store. A would understand what is to come.

WOMEN'S LEAGUE .. . a building with a labyrinth of rooms and a multiplicity of activities.

"Let's go to the league for cof-
fee," is a standard invitation after
classes.
You head toward a large brick
edifice on North University and
go down the stairs into the snack
bar where you gather with friends,
eat a sandwich and occasionally
play cards.
But what goes on in the build-
ing above you? Out of mere
curiosity, one day you decide to
investigate and discover what ac-
tivities go on in the labyrinth. of
rooms and offices in the "other"
portion of the League.
On the first floor you peek into
a large room and find another
cafeteria where meals are served
daily. You make a mental note
of this and proceed down the hall,
past the main entrance where
people are gathered around a tele-
vision set and you stop at an office
which is impressively marked,
Undergraduate Office.
Inside, you see coeds clustered
around a desk, talking animatedly
on phones and in general looking
extremely busy with administra-
tive affairs. Deciding not to dis-
turb them, you continue down the
hall and up some stairs into the
Lydia Mendelssohn Theatre where
students are preparing a set for
that evening's play.
Out the back way, you proceed
up to the second and third floors
and hurry down the corridors
glancing in the doors of the li-
brary, listening rooms, meeting
rooms, the ball room and rooms
with no official titres.
By this time, you're awfully
tired, but your curiosity is still
whetted and you continue up to
the fourth floor. On this level
you find a maid cleaning a hotel
room and you have a chance for
8, fleeting glance into a neat, trim
bedroom before ending your tour
of the League.
With your brain reeling with the
intricacies of the building and your
feet tired from so much walking,
you decide to take the elevator
down to the first floor and return
once again to the familiar envi-
ronment of the snack bar. But
you resolve never again to think
so lightly of the League, as only
a place in which to drink coffee
with friends.
