What effect does the input and output resistance of the amplifier have on the amplifier? The input resistance of the amplifier should be as high as possible. This can increase the effective output of the input signal source and reduce the effective
The use of frequency converters can greatly reduce the energy consumption. Therefore, the inverters are used in large and small equipments. The inverter runs through the entire power plant. The safe operation of the inverter becomes a key link of the power plant. Once the inverter has problems, it w
