Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an intermediate frequency differential filter. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out specific frequencies or frequencies outside of a power supply line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency has been eliminated. Currently, intermediate frequency differential filters are mainly installed on equipment using screws; however, once the screws rust, they become difficult to remove for maintenance. Utility Model Content
