Signal interference in the classroom
WebAlternating interference signals result from the following:. 1. Electrostatic (capacitive) coupling that exists between measuring circuits and devices that are at a different potential. This interference can be removed by the use of grounded conducting screens, hence the use of coaxial cable. NB: The screen must be at earth potential for this to be effective. WebOct 14, 2024 · 3. Bluetooth. Wireless devices such as headsets, keyboards, and mice can interfere with the Wi-Fi signals. Bluetooth uses a technology called frequency hopping, which means it skips around the 2.4 GHz band, up to 1600 times per second (!) When equipment that uses Bluetooth, jumps into the frequency range of equipment that uses Wi-Fi, it can ...
