IPC: H04B1/62
Filed: 1988-02-04
Abstract: PURPOSE:To attain stable reproduction without a phase rotation whichever it is analog or digital by constituting both an encoder and a decoder of a field forward loop. CONSTITUTION:An input signal is direct-inputted to an adder 3 of an encoder 2 and is inputted through a multiplier 4 of a coefficient beta to the adder 3. The output of the adder mis recorded through an amplifier 5 of a gain -1 to a recording and reproducing circuit 6 after making the input signal the inverse of (1+beta) times. Then, the reproducing signal of the circuit 6 is direct-inputted to an adder 9 of a decoder 7 and is inputted through a multiplier 8 of a coefficient alpha=-beta(1+beta) to an adder 9. The output of the adder 9 goes to the signal of the inverse of 1/(1+beta) times of the reproducing signal of the circuit 6 through an amplifier 10 of the gain -1, and the original signal is obtained as a whole. Thus, since the encoder 2 and the decoder 7 are constituted by a field forward loop, even when the present device is digitalized, the stable reproducing output without a phase turning during one sampling period can be obtained.

Title: System for synchronizing cell
Inventor: TOYOSHIMA AKIRA
IPC: H04J3/06
Filed: 1988-02-05
Abstract: PURPOSE:To reduce the number of synchronizing bits and to reduce a mis-synchronizing rate by providing the output means of a synchronizing pattern detecting signal, the output means of a detection interval counting signal, the output means of a resetting pulse, and the output means of a cell synchronizing pulse. CONSTITUTION:A synchronizing pattern detecting circuit 1 collates a cell multiple signal 100 with a synchronizing pattern, and when they coincide, the circuit 1 outputs a synchronizing pattern detecting signal 101 to a detection interval counting circuit 2. The circuit 2 counts the interval between the signal 101 and the synchronizing pattern detecting signal to be detected just before each time the signal 101 is inputted, and the circuit 2 outputs the result as a detection interval counting signal 102 to a detection interval checking circuit 3. When the detection interval is integer-fold that of a cell length, the circuit 3 sends a resetting pulse 105 to a cell synchronizing counter 5 and resets the counter 5. The counter 5 outputs a cell synchronizing pulse 106 each time it counts clock pulses for the cell length. Thus, since the fact that a synchronization is obtained is decided for the first time when a synchronizing pattern detection position interval is made integer-fold that of the cell length, the mis- synchronizing rate can be reduced even at the time of reducing the number of synchronizing bits.
