PURPOSE:To reduce a spurious component generated from a delay line, and to obtain a satisfactory delay signal, by providing plural acoustic delay lines, and switching input/output signals against these delays. CONSTITUTION:An SECAM color signal inputted to a color signal input terminal 15 is supplied to plural 1HDLs 17, 18 through an input signal changeover switch 16. On the other hand, to an input terminal 21, a horizontal synchronizing signal is inputted, and a control signal is generated by an F/F22. By this control signal, switching control of the input signal changeover switch 16 and an output signal change-over switch 19 is executed, and an output color signal of the switched 1HDL is fetched from an output terminal 20. |
