Signal excision will be defined, as well as some of its practical advantages. An acousto-optic signal excisor based on an interfero-metric spectrum analyzer will be presented. This system is capable of notch filtering 1 MHz channels across a 200 MHz RF bandwidth. Experimental results will be discussed,as well as comments on future system goals and required technology developments.
