Abstract:
A method for conversion of signals between analog and digital characterised by; applying a non-linear transfer function to an input signal, such that the relation between the quantisation levels of the converter and the input signal vary as a non-linear function of the magnitude of the input signal. The non-linear transfer function is related to the probability density function of the input signal so that larger quantisation bins of the converter correspond to less probable values of the input signal.
