A filter is a frequency-selective device that passes certain frequency components of a signal while greatly attenuating other frequency components. By using the frequency selection characteristic 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. A filter is a device that filters 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. The process is converted into time functions of voltage or current through the action of various sensors, which are called time waveforms of various physical quantities or called signals. Since the time of the independent variable is continuously valued, the time is called a continuous time signal and is also conventionally called an analog signal;
