1. BY GRID BIAS
Most readers of "Current Radio"
do not seem to be' acquainted with
the fact that. there are two common
methods of obtaining detection with
a. three element vacuum tube. nor
how detection in each case is accom-
plished. It is the purpose of this ar-
ticle to describe one of the methods
—detection by grid bias—and tomor
row we will describe the other—by
use of grid condenser and leak—
which is the more common practice.
Remember that the incoming sig-
nal is an alternating current oscil-
lating at super-audible frequencies.
In order to make these signals op-
erate a pair of headphones. we must
convert the alternating current into
direct current, and that is what the
detector does. .
Let us consider Fig. 1. Do not be
alarmed by the appearance of ap-
parently complicated "curves" be-
cause they are really quite simple to
understand once the fundamental
principles are grasped.
8n Fig 1 we have a curve (Ad?)
which shows the effect of the grid
voltage on the plate current. As
you may know, the heated filament
in a. tube throws off electrons which
act as"'carriers" for the "B" bat-
tery current from the plate to the
filament. The voltage impressed on
the grid has s. very decided effect on
the amount of current that may flow
over this carrier path of electrons
and our diagram shows a sample
curve. Thus it will be seen that with
the grid about 1 volt "negative" the
plate current will be about one~
fourth of a milllampre: at "zero"
grid voltage the plate current will be
about halfway between .6 of a mil-
lismpere and 1.0 miliiamp.
Notice that the curve has a rather
sharp bend at the bottom. The
sharper this bend is the better de-

method.
For detector action with grid bias
we operate the tube Just where the
bend occurs. as shown. Now any
incoming oscillations. such as shown
by the "incoming signal" will vary
the grid voltage. and undoing so
will vary the plate current. But if
the tube is operated on the bend
you can see. by projecting the signal
oscillations u pen the curve. "A-B",
that a kind of lop-sided amplifica-
tion takes place.
The line designated "normal plate
current." is the plate current that
would maintain it the grid current

remained constant. But the incoming
oscillations extending on each side or
this line cause—due to the bend in
the curve A~B-—the increases (1) in
the plate current to be considerably
greater than the decrease (D) below
the “normal" line. This result in a
resultant positive variation. shown
by the dotted line .and this is heard
in the phones.
In other words, the plate current
both increases and decreases in the
headphones. but the increase is so
much greater than the decrease that
the general effect is that of an in-
ed pull on the headphone diaph-

Soft tubes usually have sharper
"bends" than hard tubes. Which is
one of the reasons why a soft tube
often makes a better detector when
operated by this "bias" method. In
fact some hard tubes have 0. curve
which is almost s. straight line. and
has iitle if any bend.
