Title:
AUTOMATIC REPEATING SYSTEM
Document Type and Number:
Japanese Patent JPS5583357
Kind Code:
A
Abstract:

PURPOSE: To enable a simple constitution to repeat automatically a data signal and sound information signal easily, by separating the data signal from the sound information signal and by correcting signal levels and frequency characteristics by different correction systems.

CONSTITUTION: A transmission signal with data end signal S2 interposed between data signal S1 and sound information signal S3 is received by reception part 301; the data signal is detected by detector 305 of data signal correction system 304 and amplified 307 and the sound information signal is detected by the detector of sound information correction system 309 and amplified 312. Then, signal levels and frequency characteristics of the data signal amplified 307 and the sound information signal amplified 312 are corrected and the both are transmitted from transmission part 6 in series being superposed upon carrier f2. Therefore, this simple constitution can repeat automatically the data signal and sound-information signal easily.
