Title:
SIGNAL PROCESSING WITH SAMPLING
Document Type and Number:
WIPO Patent Application WO1997009787
Kind Code:
A3
Abstract:
A signal-processing arrangement includes a conversion circuit CONV which converts an input signal Sin into sub-ranging signals Sc(1)..Sc(N) corresponding to different amplitude sub-ranges of the input signal Sin. Each sub-range signal is supplied to a respective one of an array of sampling circuits SC(1)..SC(N) which supplies successive samples thereof to a processing circuit PROC for processing in accordance with operations which may constitute or include A/D conversion. Such an arrangement is particularly suitable for use in a television receiver, multimedia or other video image display apparatus, and various types of disc-players and tape-recorders.
