Abstract
An indoor television antenna has a bypassable amplifier circuit, which is user-controllable to switch between an amplification signal path and a unity gain signal path. The amplifier circuit, also referred to herein as a television signal switching circuit, includes a first switching circuit, a second switching circuit, a third switching circuit and a switching control circuit. The first switching circuit is coupled to the second switching circuit by the amplification and unity gain signal paths, which are substantially isolated from each other. An input of the first switching circuit is responsive to an antenna, and an output of the second switching circuit is coupled to a first input of the third switching circuit. A second input of the third switching circuit is coupled to a game port signal, and an output of the third switching circuit is ultimately coupled to a television receiver. The first, second and third switching circuits are responsive to one or more switching control signals from the switching control circuit. The first switching circuit selectively routes the television signal from the antenna through either the amplification signal path or the unity gain signal path in response to one or more switching control signals. Likewise, the second switching circuit selectively routes the television signal from either amplification signal path or the unity gain signal path to the third switching circuit in response to one or more switching control signals. Similarly, the third switching circuit selectively routes the television signal from the output of the second switching circuit or a game port signal from a game port input to the television receiver in response to one or more switching control signals.
