  • Electronic switch for TV signal booster
    Publication number: 20050285979
    Abstract: A method of automatically disabling a low noise amplifier (LNA) that serves to boost weak video signals in a TV tuner, when the television receives a cable TV service. The method involves storing the total number of preset programs assigned during an initial auto-tune setup operation. If the total count exceeds a predetermined threshold (22, 23), this indicates cable TV service whose signals will not require boosting. The LNA is then disabled to avoid picture beat from interference between programs on neighbouring channels.
