Title: Afc locking decider
Inventor: TAKENAKA TETSUYOSHI
IPC: H04B7/15
Filed: 1989-10-23
Abstract: PURPOSE:To detect the locking state of an AFC loop by providing a lock discrimination means monitoring a timewise rate of change of a control voltage and detecting it that the timewise rate of change of the control voltage is smaller than a prescribed value so as to discriminate the lock state of an automatic frequency control means. CONSTITUTION:A locking deciding section 10 consists of an averaging section 4, a comparison section 5, and a threshold level latch section 6, and the locking state is detected by detecting that the output of a frequency error detection section 1 is smaller than the predetermined threshold level epsilon. Since a signal (x) is fed to a VCO 3 via a loop filter 2 in an automatic frequency control (AFC) loop, the oscillating frequency of the VCO at a succeeding time is varied with the signal (x). When the threshold level epsilon is selected in advance to be the level at which the AFC loop is locked, the locking state is decided by detecting the time when the output of the averaging section 4 is smaller than the threshold level epsilon.

Title: Frame synchronization system
Inventor: TERADA KOICHI
IPC: H04L7/08
Filed: 1994-11-10
Abstract: PURPOSE: To continue transmission of data by using the dummy data, etc., in place of lost data in order to make a receiver device act as if the lost data were still available. CONSTITUTION: When the data are lost on a general purpose data transmission line 3, a data reception confirming part 27 finds the loss of data by a date serial number and informs a dummy data generation part 26 of this fact. The part 26 generates the dummy data and supplies them to a selector 25. Then the part 27 controls the selector 25 for selection of the dummy data, and a driver 22 sends the dummy data to a public network 1. Thus the dummy data are received with the reception timing of a frame flag and therefore the data to be interpolated are generated at the receiver side from the timing information and a framing protocol. Then the receiver side acts as if the frame flag were received.
