发明名称 FERGDEMODULATORKRETS
摘要 In the PAL system, the demodulating axis for one of the two color difference signals, i.e. the R-Y signal, is transmitted switched in phase 180 DEG at each horizontal scanning period. In order to reproduce this signal, a demodulator circuit for color television signals is provided for producing a R-Y signal of the correct polarity, using a line switching signal not controlled by the phase of the transmission signal, and having a frequency half that of the horizontal frequency.
