Title: Reproducer of digial signals
Inventor: KIHARA NOBUYOSHI
IPC: H04B1/00
Filed: 1978-04-21
Abstract: PURPOSE: To editing to be performed through cutting of PCM recording tape by  jumping the wrong data detected and reading out the next data by the use of a data  error detecting circuit and a memory circuit.  
     CONSTITUTION: Normal reproduction digital input signals are subsequently memorized in a memory circuit 1 based on the period of the clock signal 3 by an address assigning circuit 2. The contents of the memory circuit 1 are subsequently read out in synchronization to the period of the circuit 2 by a read-out address assigning circuit 4. Now, when a wrong data is inputted, it is memorized in the memory circuit 1 and is at the same time detected in a detecting circuit 6. A control circuit 8 causes the circuit 4 to jump the wrong data having been stored in the memory 1 and read out the next normal data. Since this obviates outputting of the wrong data and causes the normal signals to be outputted continuously, reproduction may be performed without production of any noise from the splices of the PCM recorded tape even if it is cut and edited.
