This, these interference are removed respectively, use two pole filter circuits here, and interference is filtered out respectively；
The power supply of 3v or 5v are connected between described two diodes；It can be generated in the electric signal of control magnechuck low
Frequency high-amplitude voltage, when the non-inverting input terminal of amplifier has the voltage signal greater than 3V or 5v, diode current flow, filter out greater than 3V or
The voltage signal of 5v；
The first operational amplifier circuit and the second operational amplifier circuit, first fortune are connected separately in the cathode of described two diodes
Discharge road and the second operational amplifier circuit formation differential amplifier circuit；This design selects differential amplifier circuit that can effectively eliminate common mode
Signal；
First operational amplifier circuit is connected to the ground, output end of second operational amplifier circuit as signal.
