Abstract
The invention seeks to provide an improved method and apparatus for detecting thresholding errors in a digital signal recovered from a transmitted signal, wherein a derived threshold error signal varies linearly with the threshold error. Extraction of a threshold error signal linearly related to the actual threshold error enables increased speed of reaction of a threshold control circuit.
