IPC: H03J7/18
Filed: 1982-02-09
Abstract: PURPOSE:To perform invariably proper channel selection switching by discriminating between a temporarily weak electric field and a weak electric field generated continuously in a fault radio wave state. CONSTITUTION:When a temporarily weak electric field is generated, its generation is detected in a weak electric field detection stage 100, but the generation of the weak electric field is temporarily and an excellent radio state is obtained soon, so a weak electric field continuation detection stage 200 judges that the generation of the weak electric field is not continuous and the excellent radio state is maintained, so that the channel selection switching of a receiver is not performed at a channel selection stage 300. When a continuously weak electric field is generated, the weak electric field continuation detection stage 200 judges that the generation of the weak electric field is continuous, so the channel selection stage 300 searches for another station having a radio wave signal level higher than a specific level automatically and the channel selection of the receiver is switch to the station.
