Abstract
In a circuit for removing crosstalk components in a carrier chrominance signal, there are provided a first delay circuit (20), an inverter (21), a first higher-voltage detecting circuit (18), a second delay circuit (22), a second higher-voltage detecting circuit (19), a third higher-voltage detecting circuit (25), a first lower-voltage detecting circuit (23), a second lower-voltage detecting circuit (24), a third lower-voltage detecting circuit (17), and an adder (26) thereby producing a crosstalk-removed carrier chrominance signal. Furthermore, the first delay circuit (20), the inverter (21), and an adder (28) form a comb filter for correcting a time delay due to said circuit for removing crosstalk components in a carrier chrominance signal.
