摘要 |
In a pre-amplifier for use in a three electrode single tube type color television type, color signals delivered from respective electrodes are processed by output signal processing circuits. Each output signal processing circuit comprises a high input impedance amplifier provided with a feedback circuit. A variable resistor is connected in the feedback circuit for adjusting the gain of the amplifier.
