Abstract
There is shown a method for correction of rapid periodic frequency characteristic errors in the reproduction of signals with periodic synchronizing signals from magnetic tape as well a circuit arrangement for carrying out the method. For repeated correction of the error within the period between two successive synchronizing signals, there are brought into account the stored error magnitudes of similarly positioned synchronizing signals on adjacent tracks, since the synchronizing signals of successive oblique tracks are offset by a fraction of a line. The circuit arrangement comprises a storage device with a number of storage places corresponding to the number of lines and/or to the number of color television signals of a television picture. In each storage place the average value of the frequency response error of previous lines of the same kind is stored and is superimposed on the actual error value.
