Abstract
A method and a circuit for resolving the out-of-phase problem between a color burst signal and a sub-carrier signal of a television system. A delay means is used which leads to the synchronization of the color burst signal and the sub-carrier signal such that a subsequent color demodulator can demodulate correct color signals. Therefore, the locking of the two signals will be fastened without any excessively large circuit hardware.
