Abstract
The invention features an optical system for removing electromagnetic interference components from a radio frequency signal. The radio frequency signal is electrically cascaded through a series of multiple channels each having a common pathway. The final RF output of the system produces a notched signal whose notch depth is the cumulative depth of each channel notch depth.
