data Subcarriers) before modulation.
data signals may be placed on additional Subcarriers.
Stereo can be multiplex, discrete, or matrix and unrelated audio and
data signals may be placed on additional Subcarriers.
A triangular 60 Hz energy dispersal waveform is added to the composite baseband signal(video plus audio and
data Subcarriers) before modulation.
Sound is on a FM subcarrier as in terrestrial transmission,
but frequencies above 4.5 MHz are used to reduce aural/visual interference.
NPUSCH The NPUSCH is used to transmit uplink data and uplink control information.
The uplink subcarrier spacing is 3.75KHz and 15KHz.
which offers more than one audio signal by adding one or two Subcarriers on the audio signal, each synchronized to a multiple of the line frequency.
In what can be considered an opposite of PAL-60, NTSC 4.43 is a pseudo
color system that transmits NTSC encoding(525/29.97) with a color subcarrier of 4.43 MHz instead of 3.58 MHz.
The color-under format of VHS uses a 629 kHz subcarrier while U-Matic
& Betamax use a 688 kHz subcarrier to carry an amplitude modulated chroma signal for both NTSC
and PAL formats.
Sometimes a channel may contain an MTS signal,
which offers more than one audio signal by adding one or two Subcarriers on the audio signal, each synchronized to a multiple of the line frequency.
