ABSTRACT:
Disclosed is a chroma scanning circuit used in a beam index type color picture reproducing apparatus, the circuit being provided with an inductance element connected in series to a horizontal deflection coil, and a scanning signal generation circuit connected to a junction between the horizontal deflection coil and the inductance element. The impedance between the junction and the earth at the chroma scanning frequency is increased by the inductance element to thereby make a chroma scanning signal generated from the chroma scanning signal generation circuit flow easily in the horizontal deflection coil.
