Abstract
Official abstract text for this publication.
The present invention concerns an apparatus for protecting a satellite reception system from strong terrestrial signals. A high Q tunable trap is used to help reject strong ATSC signals or other signals that may be present on the input coaxial cable of a satellite receiver that operates in a single-wire multi-switch (SWM) environment.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus comprising: a filter coupled to a source of a first signal and a second signal, said filter including a high-pass filter; a tunable trap filter coupled to said filter for filtering said second signal within a passband of said filter; and a demodulator for demodulating said first signal and determining a signal parameter of at least one of said first signal and said second signal and generating a control signal for controlling said tuna…
