VOLTAGE TRANSFORMER OF AFT(AUTOMATIC FINE TUNING) FOR PIP TELEVISION SYSTEM

摘要

An apparatus for switching AFT(Automatic Fine Tuning) voltage of a television having a PIP(Picture in Picture) function is disclosed. An AFT voltage change unit(40) switches AFT voltage provided from a main tuner(20) or a sub tuner(30) according to a tuner selection signal of a timer(10) based on a feedback tuner AFT voltage. Thereby, the implement of the circuit is simple and the operation of AFT is easily processed.
