Simply, the digitically is the side of the digital signal, and the simulation is analog signal.
Since the digital signals are typically rectangular, there is a large number of harmonics. If in the board
Digitally has no simulation from access point, and harmonics in digital signals are easy.
Interfering to the waveform of the analog signal. When the analog signal is a high-frequency or power signal, it will also
Affect the normal operation of the digital circuit.
The root cause of the problem is that no one can guarantee that the resistance of the copper foil on the circuit board is zero.
Separating the digitally and simulated ground in the access point, is to put digitally and simulated ground
A total of electrical resistance falls to the smallest.
