  • Signal switching apparatus
    Patent number: 9054784
    Abstract: A signal switching apparatus includes a switch circuit having a common terminal and first to third terminals, and enabling two terminals among the first to third terminals to be simultaneously connected to the common terminal while enabling the first to third terminals to be individually attachable/detachable to/from the common terminal, and an amplification circuit of which an input terminal is connected to the first terminal, and an output terminal is connected to the second terminal. Here, gain in the output terminal being an output point, with respect to a signal level in the common terminal being an input point, is switched to a first gain when only the first terminal is connected to the common terminal, a second gain when only the second terminal is connected to the common terminal, and a third gain when the first and second terminals are simultaneously connected to the common terminal.
