Abstract
An improved charge transfer device signal processing system is disclosed. In one aspect of the invention the signal at each node of a bucket brigade delay line is detected to provide a continuous output signal over a major portion of a cycle of a multiphase clock. In a different aspect of the invention the signals detected at the respective nodes of a matched filter are selectively summed to negative or positive summation busses to provide an electronically programmable matched filter. In still a different aspect of the invention a charge transfer device matched filter is provided in which both the magnitude and sign of the respective weighted signals can be selectively controlled. There is also provided an improved configuration for detecting the charge required to recharge the two different electrode portions of a split electrode weighted charge coupled device matched filter.
