Technical Field

The application relates to the field of filters, in particular to an anti-impact medical high-frequency non-electromagnetic filter shell.

Background

A filter is a frequency-selective device that passes certain frequency components of a signal while significantly attenuating other frequency components. By using the frequency selection function of the filter, interference noise can be filtered out or spectrum analysis can be carried out. In other words, any device or system that can pass a specific frequency component of a signal and greatly attenuate or suppress other frequency components is called a filter. The filter is a device for filtering waves. "wave" is a very broad physical concept, and in the field of electronics, is narrowly limited to refer specifically to processes that describe the variation of values of various physical quantities over time. This process is converted into a time function of voltage or current, called time waveform of various physical quantities, or called signal, by the action of various sensors. Since the argument time is continuously valued, it is called a continuous time Signal, which is also conventionally called an Analog Signal (Analog Signal).
