If the voltage on the grid is
changed, however, the normal plate
current will increase or decrease de-
pending on whether the grid voltage
is changed in the positive or negative
direction respectively. 1t is easily
seen, however, that since the charac-
teristic curve Is bowed more at the
bottom end than at the top end, the
increases in the positive direction or
toward the right of the grid voltages
will cause greater increases In the
plate current than the decreases
caused when the grid voltage swings
an equal amount in the negative
direction-that is, toward the left, so
that the greater the amplitude of the
oscillations, the greater will be the
current flowing in the plate circuit.
Show the Changes.
These examples are given merely
to show the changes which take
place in the plate circuit of a tube
when changes occur in the grid cir
cult Of the tube. When the continu-
Gus radio frequency waves are
modulated or formed by the voice
waves, the variations are reproduced
as varying currents, which produces
an audible response in a pair Of tele-
phones connected in the plate circuit
Of the tube.
The audio frequency current, how
ever, is not only current present in
the grid circuit but is the envelope"
current produced by the radio fire.
quency current in the plate circuit
as shown in Figure 2.
In the ordinary type OF non-regen-
erative detector circuit no use is
made of this radio frequency current
in the plate circuit, but in the re-
generative types of circuits this radio
frequency current in the plate circuit
performs a very important function.

TO WIDEN AVENUE BY CONDEMNATION
McLendon Orders Property Taken Over On First
 Avenue Stretch

Declaring that the city commission can wait no longer for First avenue property owners to settle with the city in the effort to acquire right-of- way for widening and paving of the thoroughfare between Forty-first and Forty-seventh streets President D. E. McLendon served notice Mon- day that condemnation proceedings would be started without further mo- tice.
 We must get this work started in the next few weeks," he said, and property owners have had ample time to make settlements. Several more came up today and settled, but a few are holding out, and there is nothing left to do but start legal proceedings h these cases.'
 The commission head said he would place all the necessary data in the hands of City Attorney W. J. Wynn Tuesday and instruct him to proceed to acquire the right-of-way needed to pave and widen the avenue.
 Before the plans for the project are finally completed, MT. McLen- don said, a conference will be held with the B. R., l.. & Pc. Co.,, which he believes will result in decision of the company to bear the expense of paw ing between It's tracks on the. avenue. The company originally declined to do this unless given the privilege Of parking the avenue.
