The optical excision processor is useful for rejecting narrowband interference from broadband signals for improved broadband signal detection. Key performance measures of the optical excision processor include filter resolution, filter depth, and spurious free dynamic range. This paper presents the theoretical limits of these key performance measures for the optical excision processor and relates these performance limits to quantified improvements in broadband signal detection.
