To quickly assess the difficulty of the text, read a short excerpt:
The circuit shown in Figure 94 is in all respects similar to Figure 93 with the exception that the balancing out circuit includes a vacuum tube V-3 which amplifies the effect of generator A-l. Better balance of the opposing E. M. F. 's is thus secured. It is thus seen that in a general way the circuits of Figures 93 and 94 simulate the circuits of wire telephony, the apparatus always being in a position to transmit and receive. A system involving the use of separate aerials for transmission and... 142 Vacuum Tubes In Wireless Communication Wireless Telephony 143 reception of speech signals disclosed by Espenschied is shown in Figure 95. The aerial of the transmitter is indicated at W, and of the receiv- ing station at W-l. The source of radio frequency current for the carrier wave is shown at A-l, the output of which is amplified by means of the three-electrode vacuum tubes V-l and V-2, the output currents of the latter tube being fed to the aerial W at the coupling P, 8. The receiving system embraces the coupling transformer P-l, S-l, the incoming signal being amplified by the three-electrode tube Y-3 and detected by the tube VA.
