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, paired analog shift registers are used. While one register has samples of one video line signal clocked into it at a rate corresponding to its time base instability, the other register clocks out, at a uniform rate, analog signals of the previous line, and vice versa.
