Defect compensation for color television
摘要:
A defect compensation circuit which substitutes a portion of delayed signal information for a real-time signal defect. A capacitor passes the a-c component of the delayed signal and stores the d-c component of the real-time signal to preclude the occurrence of d-c shifts upon effecting the substitution of signal.
