WIDEBAND TUNABLE NOTCH CANCELLATION

A system and method for wideband tunable notch cancellation that is passive and does not require feedback or feed forward circuitry. An input spectrum containing interference is split into two signals that are 180 degrees out of phase with each other. The preferred signal is filtered out of the 180...

Zusammenfassung:	A system and method for wideband tunable notch cancellation that is passive and does not require feedback or feed forward circuitry. An input spectrum containing interference is split into two signals that are 180 degrees out of phase with each other. The preferred signal is filtered out of the 180 degree out of phase signal using a notch filter while the original signal is sent through a delay line. Then the two signals are summed with a power summer so that the interference signals that are 180 degrees out of phase with those in the original signal are cancelled out and the preferred signal remains. The notch filter is tunable to different preferred signals.
