Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a network filter base. Background Art

[0002] The function of the filter is to allow signals of a certain frequency to pass smoothly, while signals of other frequencies are greatly suppressed. It is essentially a frequency selection circuit. In the filter, the frequency range in which the signal can pass is called the passband or passband; conversely, the frequency range in which the signal is greatly attenuated or completely suppressed is called the stopband; the dividing frequency between the passband and the stopband is called the cutoff frequency; the voltage gain of an ideal filter in the passband is a constant, and the voltage gain in the stopband is zero; there is a transition band with a certain frequency range between the passband and the stopband of an actual filter.

[0003] When the network filter is in use, it needs to be installed on a base. When the network filter is used for a long time, it needs to be regularly disassembled from the base for maintenance.
