• What’s the piezoelectric ceramic filter?

  A filter is a circuit or device that is selective to the frequency of the signal. To separate a signal at a certain frequency or a signal in a certain frequency band from a signal with a wide frequency range, a filter is required. For example, in multi-channel communication, if two or more people on
