ABSTRACT:
A method and system for reconstructing quantized signals is described. Non-linear filtering is applied to a quantized signal to distribute quantum changes over their respective time intervals to provide, for example, a smoother reconstructed signal. The quantization bounds are enforced for each refined signal point to ensure a reconstructed signal that is within the bounded uncertainty associated with the original signal. The process can be applied to selected control points of the quantized signal and non-overshooting splines can be used to interpolate therebetween.
