FREQUENCY SELECTION FEATURES IN RECEIVING DEVICES

Abstract

This article discusses the concept of Radio Frequency Interference (RFI) as a disturbance caused by electromagnetic signals that interfere with the normal operation of electronic devices and systems, and RFI is a significant problem in modern technology, where devices often have wireless signals and RFI is specifically focused on the disturbance of signals in the radio frequency range, unlike Electromagnetic Interference (EMI), which covers a wider range of disturbances and environments. With the increasing use of wireless communication technologies such as Wi-Fi and Bluetooth, the importance of addressing RFI is increasingly emphasized.
