            The circular inductors

            Introduction of Instrument Coil:

            The circular inductors are what we often call ring-wound inductors. It is made of a spiral wire. For DC signals, as long as it is a wire, it can be turned on. However, for high-frequency signals, the transmission of signals is carried out by the alternation of electric and magnetic fields in space. The inductance will generate a magnetic field for the alternating electric field, which hinders the changing strength of the alternating magnetic field of the signal, thereby hindering the transmission of high-frequency signals. From the point of view of simulation, the inductance passes through DC and blocks high frequency, so it is equivalent to a low-pass filter, which mainly plays the role of suppressing high-frequency signals.
