Abstract

PURPOSE:To obtain an accurate fH/8 offset by generating a signal of (fSC+ 40fH+fH/8) by using a signal of (40fH+fH/8) and a signal of fSC during recoding and reproduction of a PAL system signal. CONSTITUTION:A chromaticity signal is inputted from a switch 3, a horizontal synchronizing signal from a terminal 13, and a head switch pulse from a terminal 27. A frequency dividing circuit 34 divides the frequency of the horizontal synchronizing signal by 321, and a VCO35 oscillates at 321fH. A frequency dividing circuit 36 divides the output frequency of the VCO35 by two to supply a signal of 160fH+fH/2 to a frequency dividing circuit 16, which outputs an accurate 40fH+fH/8 signal. A VXO22 compares the phase of a burst signal from a switch 21 with that of a PD23 to oscillate at fSC. Consequently, the output of the VXO22 and that of a four-phase shifting circuit 18 are multiplied mutually by a multiplying circuit 19 to obtain an accurate offset of fSC+40fH+fH/8 from a BPF20.
