Most people consider the return current when considering a fully differential circuit, but when considering the more usual circuit where a signal is referred to 'ground' it is common to assume that all the points on the circuit diagram where the ground symbol is to be found are at the same potential.

分析差分电路时，绝大多数工程师都会注意到返回电流，但对于常见的所谓单端电路，即所有信号采用相同参考点的电路，往往会认为电路中所有标有参考点符号的地方电平都相等。

Because any reports on the active control of rotating disk haven't be seen in China up to now, and this experiment research is important, so the complete set of active control system of rotating disk are built independently. The push-pull type electromagnet is applied to control the vibration of the circular disk. The power amplifier circuit that can respond to wide scope in frequency from DC to AC is designed by improving the existing circuit. The sensor signal is first low-pass filtered, then the proportional control plus the differential control circuit easy used in practice are applied to finish the more effective control. The electromagnetism shield is used as possible to decrease the signal disturbance from the electromagnet to eddy sensor.
