ABSTRACT:
Improvements to timebase correction devices utilizing clocked analog delay lines are shown. Problems of clocked analog delay lines such as timing errors in the phase of internal sample and holds with respect to their clock, drifting of the gain and offset, and high frequency noise are corrected by use of external sample and hold circuits, external delays, automatic gain and offset circuits and high frequency preemphasis circuits.
