Abstract
A signal enhancement system is provided using an improved digital filtering apparatus and method. Enhanced performance and cost is achieved by processing signals on the fly in real time. Greater precision is achieved by providing compositing-after-correlation capability. Further improvements are achieved by separating and compositing a plurality of signals that are multiplexed together. Still further improvements are achieved with a filter implementation using charge coupled devices.
