(8) Chroma Signal Filter ( Chroma Filter )
Chroma input signal components ( Cb, Cr ) prior to the modulation go through a 1.3 MHz Band Limiting Filter
( see 4:2:2 to 4:4:4 x2 interpolator in the block diagram ).
Chroma signal which is modulated by the sub-carrier is output via a low pass filter ( Chroma LPF in the block diagram ).
Frequency response of each filter is shown below.
