Abstract
A technique is disclosed to independently tune different sections of a filter by momentarily frequency shifting a first tuned section, preferably by shorting certain nodes in the first tuned section, such that response of a second section can be determined and independently tuned. The first section is returned to normal operation after the second section is tuned.
