The principle and production process of this circuit are as follows: Infrared receptor apex REM can select currency integration infrared receptor apex, the shape is shown in the figure 1, the infrared remote control signal received by REM is amplified by V1, V2, and the signal drives infrared transmitting tube work. Except for broken line part of figure 1, the other is put in the living room, infrared emitter diode connects coaxial line and receiving part, then be put front shadow of bedroom satellite receptor. When you possess of this device, you can select TV program that you want conveniently in living room.
