Abstract
In order to couple together vertical-frequency synchronization signals generated by a computer connected to an data transmission system, the synchronization signals are generated by counting the clock pulses. A reference signal is transmitted to the computer or processor; the reference has a frequency which is a whole-number fraction of the desired frequency. Upon receipt in the processor (16) of the reference signal, a counter (19) provided for counting of the clock pulses is preset.
