Output selection of multi-output filter

摘要

Described is a filtering arrangement in which a first filter is configured to exhibit a first frequency response FR and has a first node and a second node; a second filter is configured to exhibit a second FR and has a first node and a second node; and a third filter is configured to exhibit a third FR and has a first node and a second node. A first common node interfaces the second node of the first filter with the second node of the second filter; and a second common node interfaces the first node of the second filter with the first node of the third filter. The second FR exhibited by the second filter isolates a first signal on a first signal path between the first node of the first filter and the first common node from a second signal on a second signal path between the second common node and the second node of the third filter.
