Abstract :
Applications for real-time adaptive filtering techniques are in such diverse fields as adaptive control, ghost cancellation in TV transmission, channel equalization for communication and magnetic recording and estimation/prediction for speech recognition. A block diagram of a ghost-cancellation system for terrestrial and cable TV transmission is shown. The single-chip adaptive filter based on an integrated CCD and CMOS implementation described combines the power and weight advantages of charge-domain computing units with the versatility and adaptability offered by digital control and memory units to achieve a low-power implementation.<>
