摘要
This disclosure deals with a novel scrambled television decoding system for modulation-suppressed trains of synchronizing signals at a predetermined line rate, in which the demodulating circuits produce an advanced modulation frequency signal synchronized with a selected reference first equalizing pulse to control the gain of the received scrambled television signals and correspondingly to restore the suppressed synchronizing signals to reconstitute the unscrambled television signal.
