A signal transition detection circuit detects a transition which satisfies predetermined criteria related to magnitude and time. These criteria include that the magnitude of a group of signal samples preceeding the transition and a group thereof following the transition each be relatively close in magnitude and that the difference between the magnitudes of signal samples preceeding and following the transition be at least a predetermined amount. Further, detection criteria are included to test for smoothness and monotonicity of the transition and to exclude detection of transitions having magnitude changes exceeding a predetermined amount.
