Abstract
A skew code generator for digitally quantizing the width of a pulse. A series connected string of identical voltage controllable delay elements is supplied with the pulse, which is sensed as it passes through each of the delay elements. Output signals are developed in response to the leading edge of the pulse and are latched in response to the trailing edge of the pulse. An encoder generates a binary output from the latched output signals, which is indicative of the width of the pulse.
