AUTOMATICALLY SETTING AN OPERATIVE STATE OF A WIDEBAND AMPLIFIER |
摘要 |
<p>A multi-channel receiver (200) comprises: an input (111) for receiving a wideband signal potentially comprising multiple channels, a tuner stage (110), a wideband amplifier (201) connected between the input (111) and the tuner (110), a controllable switch (202) bridging the amplifier (201) and a switch controller (203) designed to generate a switch control signal (BSC). For controlling the switch, the switch controller (203) is designed to measure at least one signal quality parameter and to generate its switch control signal (BSC) on the basis of the measured parameter. The decision of switching the switch (202) to its open state (amplifier active) is exclusively taken during at least one time interval when the receiver is switched to a channel.</p> |
