Abstract
In this paper, the variation of gain vs frequency of analog low pass filter in the atmospheric environment, electromagnetic environment, and electromagnetic shielded environment are compared. An electromagnetic wave environment on MATLAB has been created, in which electromagnetic waves propagate in the x direction, its electric field component is aligned in the y direction and the magnetic field component is aligned in the z-direction. Analog low pass filter characteristics have been implemented in, an electromagnetic wave environment. Then the comparison of characteristics of analog low pass filter in the atmospheric environment, electromagnetic environment, and electromagnetic shielding environment has been done. And the results obtained after comparing are examined. It has been observed that electromagnetic waves accumulated on shielding material. After providing a shield to the low pass filter circuit, the original characteristics of the low pass filter have been recovered.
