ABSTRACT:
Time base instability of signals in a train thereof is corrected by use of analog shift registers. As employed in the correction of time base instability of video signals, plural analog shift registers are used. Two clock rates are used, respectively, to clock video signals into and out of the analog shift registers. The clock-in rate is set so that samples of a video signal which has been stretched a predetermined amount may load all stages of an analog shift register within the duration of the stretched signal. The clock-out rate is set to unload all stages of an analog shift register within the nominal duration of a video signal.
