PURPOSE:To make it possible to change over correction signals of a frequency- characteristic improving circuit for color signals smoothly by selectively using a divider circuit bringing switching elements, connected between a current supply and divider circuits, under control. CONSTITUTION:The output terminals of divider circuit M1 for obtaining correction signal XA and divider circuit M2 for correction signal XB are connected in common, and current supply 15 is shared. Switching transistors Qa and Qb, connected between current supply 15 and divider circuits M1 and M2, are controlled to use divider circuits M1 and M2 selectively. |
