ABSTRACT:
An adaptive digitizer circuit for an information processing system includes an entropy filter responsive to an information signal V having a variable noise .sigma..sub.V that is a function of V, for providing a transform signal T, having a constant transform noise level .sigma..sub.T throughout its dynamic range; and an analog to digital converter in which the ratio .sigma..sub.T /.delta..sub.T of the noise level .sigma..sub.T of the transformed signal and the digitization interval .delta..sub.T is constant throughout the dynamic range of T.
