Monochrome and
Colour Television
However, the eye is least sensitive to colours that lie around the ±Q signals, and
therefore it is allowed a bandwidth of only ±0.5 MHz with respect to the colour
subcarrier. It may be noted that both 7 and Q signals are active up to 0.5 MHz and
...

Colour Television: Theory and Practice
As we increase the gap between the vision and the colour subcarrier, this dot
pattern becomes less and less troublesome. It can be further minimised by
restricting the bandwidth of the colour (chrominance) signals. Thus, the possibility
of ...

Digital Video and HD: Algorithms and Interfaces
With frequency interleaving, the colour subcarrier frequency is chosen to
alternate phase line by line, so as to minimize the visibility of encoded colour on
a monochrome receiver. The line-to-line phase relationship makes it possible to ...

TV and Video Engineering
In the colour TV receiver, this is further reduced by a notch filter tuned to the
colour subcarrier, in the Y channel. Another objectionable interference is likely to
be produced in the picture due to the beat between the sound IF and the colour ...
This carrier is also called colour subcarrier frequency. This colour subcarrier
frequency is located towards the higher frequencies in the channel to avoid
interference with monochrome signal frequencies. Fig. A.4.6 shows the details of
channel ...

5. In order to avoid interference between colour signal and luminance signals,
the colour signal is displaced by another quarter line frequency of 3.9062 kHz. 6.
Thus, colour subcarrier frequency Fes' = 283.5 x f,i = 283.5 x 15625 = 4.4296875

Modern Television Systems
These parts of the picture may correspond to frequencies close to those of the
colour subcarrier and in some cases the receiver's decoder will be unable to
separate this black-and-white information from the colour information, giving rise
to the ...

It is absolutely essential that the colour subcarrier generated in the receiver has
exactly the same frequency and phase as that employed at the transmitting end.
For this, 8 to 10 cycles of the colour subcarrier oscillator output at the encoder are
...
The passband is approximately 3 MHz centered around 4.43 MHz colour
subcarrier frequency. The isolated chrominance signal is given to first
chrominance amplifier. The output of first chrominance amplifier is given to
second chrominance ...
