Two TL084, one 9018 transistor and one LM386 sine wave amplifier: The second stage is implemented by the transistor 9018, the first and third stages are implemented by the operational amplifier TL084,
As the global industry demands electronic products to be "light, thin, short and small", the miniaturization of GPS systems has become a trend, and the size of GPS antennas has become a bottleneck in
The cleanest factory!Saudi Basic Industries Corporation (SABIC) has signed a major agreement to transform its polycarbonate plant in Cartagena, Spain, into the world’s first large-scale chemical produ
As shown in the figure, when the positive input pin is floating (not connected to V1), the ground voltage at A is 7.721V. Where does this high voltage come from? Because my system does not have such a
