RFI and EMI - Contacts, Fingerstock and Gaskets

An amplifier is an electronic device that increases the strength of a weak electrical signal. It is commonly used in a variety of applications, such as audio and radio systems, to increase the power of a signal and make it suitable for further processing or transmission. Radio frequency interference (RFI) and electromagnetic interference (EMI) are types of electromagnetic disturbances that can affect the performance of electronic devices. RFI is caused by the emission of RF signals from electronic devices, while EMI is caused by the emission of electromagnetic fields from electrical and electronic equipment. To prevent RFI and EMI, electronic devices can be equipped with contacts, fingerstock, and gaskets. Contacts are conductive surfaces that can be used to connect electronic components together and form an electrical circuit. Fingerstock is a flexible and conductive material that can be used to create a gasket or seal around the edges of an electronic enclosure. Gaskets are compressible materials that can be used to fill gaps between two surfaces and prevent the passage of RFI and EMI. These materials can help reduce the effects of RFI and EMI on electronic devices and improve their performance.
