Abstract
A switchable synchronizing-signal generator suitable for several television standards, information being supplied from a series arrangement of a clock pulse generator and frequency dividers to a synchronizing signal generator. The generator has a position for the N-standard which is a modified position for the M-standard, because the supply of pulses of double the line frequency to a divide-by-525 dividers is blocked during 50 line periods of each field period.
