The "Granit-8" telephone line protective device is used to protect the telephone sets for the acoustoelectric speech information leakage channel. The experimental study of the protective equipment characteristics is carried out by simulation methods in the NI Multisim environment. As a result of the simulation, the concept of the device is upgraded, and the technical characteristics are improved.
