Abstract

PURPOSE:To separate the control signal block and the data block easily and exactly, by differentiating an output of the pulse generating circuit which is triggered by an output of the synchronizing separator circuit, and using a signal which has processed the said output by the delay circuit, the counter, etc. CONSTITUTION:A vertical synchronizing pulse, an equivalent pulse and a horizontal synchronizing pulse, which has been separated from in the regenerative signal by the synchronizing separator circuit 1 are input to the differentiating circuit 12, and an output of the differentiating circuit 12 resets the bit counter 20. Also, the vertical synchronizing pulse in an output of the synchronizing separator circuit 1 is separated by the integrating circuit 15, and a reset signal of the counter 21 is formed by the comparator 18. An output of the counter 21 is applied to the control signal block gate 22 and the data block gate 23. The regenerative signal is already applied to these gates 22, 23, and the control signal block and the data block are separated by these gates.
