APPARATUS FOR RECEIVING ENCODED FACSIMILE SIGNALS WITH MINIMIZED EFFECT OF PULSE JITTER INTRODUCED NG TRANSMISSION

摘要

Black and white runs of scanned image signals are encoded into binary information at a transmitting station, transmitted over a transmission link and received by apparatus at a receiving station. Jitter introduced during the transmission is detected by the apparatus prior to the decoding of the received signal to produce an error indicating pulse which is utilized to effect erasure of the image signals of the line scan in which the jitter has occurred to leave the line as a white run. As an alternative, the erased line is filled with the signals on the next line scan to thereby visually improve the quality of reproduced image.
