Abstract:
A method for calibrating analog-to-digital conversion, comprising the steps of:converting an analog input to a clipped digital output, said clipped digital output including a plurality of clipped values and a plurality of non-clipped values; estimating at least one parameter related to said analog input based, at least in part, on said plurality of clipped values and said plurality of non-clipped values; predicting a plurality of predicted values corresponding to said plurality of clipped values based, at least partly, on said plurality of non-clipped values and said at least one parameter; digitally reconstructing at least a portion of said analog input based, at least partly, on said plurality of predicted values and said at least one parameter to produce a plurality of reconstructed values; and comparing said plurality of reconstructed values to said plurality of non-clipped values and said plurality of predicted values.
