Abstract
A signal transition enhancement circuit detects transitions in the magnitudes of successive sampled data signals and substitutes certain data samples preceeding and following the transition for certain other data samples within the transition, thereby to decrease the number of data samples required to complete the transition. As a result, the rise and fall times of signals developed in response to the sampled data signals will be reduced. A transition is detected when respective sampled data signal magnitudes within two groups of successive samples are respectively relatively close in magnitude and the magnitudes of two selected signal samples differ by at least a predetermined amount.
