Title: Separating circuit
Inventor: NOMURA KENICHI
IPC: H04L25/40
Filed: 1990-05-22
Abstract: PURPOSE:To decrease the operation speed of a frame synchronizing circuit by separating a block-interleaved nB1P code and converting the speed, thereafter, taking the frame synchronization. CONSTITUTION:With respect to block-interleaved nB1P data, the number of '1' levels in (n+1) bits is counted repeatedly by a parity counting circuit 4. In the case a position where the nB1P code is started and a position where the circuit 4 stars counting coincide with each other, a pulse for which the circuit 4 outputs to an error rate detecting circuit 5 coincides with the error of input data. On the other hand, in the case these positions do not coincide with each other, the output of the circuit becomes about 1/2 as an error rate. The circuit 5 monitors the output of the circuit 4, and in the case the error rate is large, it is decided that the circuit 4 is not synchronized with the nB1P code, a clock supplied to the circuit by a clock stopping circuit 6 is decided to be one bit missing and the position where the circuit 4 starts counting is delayed by one bit, the output of the circuit 4 is monitored again, and it is repeated until the error rate of the output becomes smaller enough than 1/2.
