balance principle of twisted pair and shielding effect of shielding layer has very good electromagnetic compatibility (EMC) characteristics. Most end users in Europe will opt for a shielded wiring system, especially in Germany, where about 95% of the users are installed as shielding systems while the other 5% are installed as optical fibres.
At present, the shielding cabling system has been recognized by more and more users for its good performance

There are still many things worth learning about the shielded cabling system. Here we will explain some common problems of the shielded cabling system in the form of a Q , this includes an introduction to EMC and the principle of the shielded wiring system. We hope to provide you with more knowledge.
The shielded cabling system originated from Europe. It adds a metal shielding layer to the outside of a general unshielded cabling system, the function o

This digest is self-aware. Question 0: Why can we separate the ground in a digital analog hybrid circuit? Some of my answers have not been approved by anyone before. If there is any infringement, please contact the blogger's email to delete it. Thank you.@ Operation amplifier answer
The following is the original article: @ magic sub's answer is inaccurate for the following reasons:First, 0 euro resistance is not convenient for debugging. I have never broken the connection between analog
Shielding wiring system from Europe, it is in the general unshielded wiring system outside the metal shielding layer, the use of metal shielding layer of reflection, absorption and skin effect to prevent electromagnetic interference and electromagnetic radiation function, shielding system comprehensive utilization of twisted pair of balance principle and shielding layer shielding role, Therefore, it has very good electromagnetic compatibility (EMC) ch

To connect a task process to a service process through a network, you must specify the IP address of the service process.
Now, you can try the effects of distributed processes. Start the taskmanager. py service process first:

After the taskmanager process sends the task, it starts to wait for the result queue results. Start taskworker. py now:

After the task_master.py process sends the task, it begins to wait for the result queue. Now start the task_worker.py process:

problems, especially the EMC and EMI Problems in High-Speed PCB wiring. There are many conflicts and they are a headache. How can we solve these conflicts?
Answer: 1. Basically, it is right to divide and isolate the modulus/number. It should be noted that the signal line should not be crossed through a separate place (moat), or the returning current path of the power supply and signal should be too large.2. the crystal oscillator is a simulated posit
