PURPOSE:To suppress the generation of a undesirable radiation by connecting the output impedance of an amplifier to the transmitting side terminal of a signal transmission line in parallel with the transmission line and by connecting a receiving impedance and a load in parallel at the receiving side terminal. CONSTITUTION:An output impedance 11 of a signal processing circuit is connected to a transmission line 2 in parallel at a transmitting side terminal 15 of the signal transmission line 2 which configures a signal transmitting circuit and simultaneously a load 3 is connected at a receiving side terminal 17 of the signal transmission line 2. That is to say, in the signal transmitting circuit which transmits the signals from a driving circuit base plate 1 through the transmission line 2 to a picture tube base plate 3, make the output impedance 11 of a transistor 12 which amplifies the voltage of a signal source 4 located on the driving circuit base plate 1, the characteristic impedance of the transmission line 2 and the value of a receiving end impedance 7 located on the picture tube base plate 3 equal so as to suppress reflected signal waves. Thus, without making the voltage of the output signal source 4 of an amplifier to be twice as large as the supply voltage to the load 3, making it the same amplitude and a matched transmission of signals is realized. |
