Circuit Detects and Locates Hidden RF Bugs

By: Tom Au-Yeung

摘要 : This design idea showcases a circuit that detects RF \"bugs,\" such as hidden wireless cameras, eavesdropping microphones, and other spying devices that emit RF frequencies in the 100MHz to 3000MHz range. A modification to this circuit not only detects RF bugs, but also locates their hidden positions.
