Abstract

PURPOSE:To need the wide band for the pen signal as well as to avoid the effect of the transmission line loss by using both the X and Y signals to carry out transmission via the relative amplitude difference between the two signals. CONSTITUTION:In A the ON of the pen signal is made to correspond to amplitude (X) of the X signal>amplitude (Y) of the Y signal, and the OFF is made to correspond to Y<X respectively. In other words, the pen signal is made to correspond to the relative amplitude difference between the X and Y signals. Both the X and Y signals sent from telautogram signal generator 11 feature the same amplitude and correspond to the binary state of ON/OFF of pen signal P at amplitude limiter 25 and 26 to receive amplitude control (A) of X>Y and Y<X and then to be transmitted to transmission line 16 after compound 15. At the receiver side, isolation 17 and 19 are given along with FM modulation 18 and 22 to obtain both the X and Y signals, and the amplitude is compared between the both signals through differential amlifier 27. In this instant, the loss of line 16 is reduced, so the state of X>Y and Y>X are directly identified at the transmitter side. Thus, signal P is produced to be supplied to telautogram output device 24.
