    7. Multi-point grounding Multi-point grounding is recommended for high-frequency circuits. At high frequencies, even a small section of the ground wire will have a large impedance voltage drop. With the effect of distributed capacitance, it is impossible to achieve a little ground. Therefore, a p...

  • Anti-jamming technology for analog sensors(6)

    6, one point ground   It is generally recommended to use one point grounding in low-frequency circuits. It has radial grounding lines and bus grounding lines. Radial grounding means that the functional circuits in the circuit are directly connected to the zero-potential reference point by wires: ...
