Abstract

The invention provides a single-tube learning amplifying circuit which comprises a micro control unit and an infrared receiving network. The micro control unit includes a power supply monitoring module and an adjustable loading resistor, wherein the power supply monitoring module is connected to a working voltage in an inputted mode, the power supply monitoring module is connected to a core processor in an inputted mode, one end of the adjustable loading resistor is connected to the working voltage, and the other end of the adjustable loading resistor is connected to a comparator negative terminal input port. According to the single-tube learning amplifying circuit, the problem of learning performance decline, caused by the fact that a remote control battery level is reduced, can be markedly improved, and therefore learning effect on the condition of a low voltage can be ensured, and cost of production and products is effectively reduced.
