Abstract

PURPOSE:To easily convert plural modified color video signals holding a frequency band in common, by a luminance signal and a color signal, by providing a band pass filter and a switching signal generator. CONSTITUTION:An input signal which has been applied to an input terminal 3 is also inputted to a mode detector 18 consisting of a BPF19 and a switching signal generator 20. A passing frequency of the BPF19 is selected, for instance, to 2.56MHz, and its output is supplied to the switching signal generator 20. The switching signal generator 20 generates a control signal for changing an operating frequency area of a BPF4, a VCO10 and an LPF14. In case when a signal as shown in the figure is supplied to the input terminal 3, the BPF19 sends an output to the switching signal generator 20, and changes over a passing frequency of the BPF4, an oscillation frequency of the VCO10 and a cut-off frequency of the LPF14 to 2.56MHz+ or -500kHz, 6.14MHz and 3.06MHz, respectively.
