Date :Définition
In some television system. Pulses at twice line-frequency occurring just before and after the field synchronization signal; with integration these are used to secure uniform field-sync. pulses with a view to improving interlacing.
The equalizing pulses and serrations in the vertical pulse occur at half-line intervals with the frequency of 31 500 Hz. One of the pulses occurring just before and just after the vertical synchronizing pulses in a television signal and serving to minimize the effect of line-frequency pulses on interlace. The equalizing pulses occur at twice the line frequency and serve to make each vertical deflection start at the correct instant for proper interlace.Termes :
