Dongguan 2016 Guancheng Electrician Mechanical Repair Training has a high pass rate and a certificate is obtained quickly

Filtering technology is used to suppress conducted interference transmitted along wires, mainly for power supply interference and signal line interference. A filter is a frequency-selective network of inductors, capacitors, resistors, or ferrite devices that can be inserted into a transmission line to suppress the propagation of unwanted frequencies. Another filtering method is software filtering unique to intelligent instruments. Software filtering can filter various interference signals including interference signals with very low frequencies (eg.). A digital filter program can be shared by multiple input channels of the instrument. Commonly used software filtering methods include the following.

In order to prevent high voltage, large current, high power and other strong currents or long transmission lines from generating Various interference signals enter the interior of the instrument and affect normal operation. The information transmission path can be electrically isolated, that is, the electrical connection between the two parts of the line before and after isolation is electrically independent of each other. The two systems each have an independent power supply and Reference potentials transmit information by non-electrical means. <>① Photoelectric isolation. Optoelectric isolation uses light as a medium to transmit signals at both ends of the isolation. The device used is an optocoupler. Since the optocoupler does not directly couple its input and output electrical signals when transmitting information, but uses
