arrangement shown in Fig. 9.3a. The four 3-channel-multiplexed signals, termed pregroups, are then combined to form the 12-channel group. This approach eases the filtering requirements but does require an additional mixer stage, which adds noise to the process. The main group designations in the CCITT modulation plan are: Group. As already described, this consists of 12 VF channels, each occupying a 4-kHz bandwidth in the multiplexed output. The overall bandwidth of a group extends from 60 to 108 kHz. Supergroup. A supergroup is formed by FDM five groups together. The lower sidebands are combined to form a 60-VF-channel supergroup extending from 312 to 552 kHz. Basic mastergroup. A basic mastergroup is formed by FDM five supergroups together. The lower sidebands are combined to form a 300-VF-channel basic mastergroup. Allowing for 8-kHz guard bands between sidebands, the basic mastergroup extends from 812 to 2044 kHz.

Super mastergroup. A super mastergroup is formed by FDM three basic mastergroups together. The lower sidebands are combined to form the 900-VF-channel super mastergroup. Allowing for 8-kHz guardbands between sidebands, the super mastergroup extends from 8516 to 12,388 kHz. In satellite communications, such multiplexed signals often form the baseband signal which is used to frequency modulate a microwave carrier (see Sec. 9.6). The smallest baseband unit is usually the 12-channel VF group, and larger groupings are multiples of this unit. Figure 9.4 shows how 24-, 60-, and 252-VF-channel baseband signals may be formed. These examples are taken from CCITT Recommendations G322 and G423. It will be observed that in each case a group occupies the range 12 to 60 kHz. Because of this, the 60-VF-channel baseband, which modulates the carrier to the satellite, differs somewhat from the standard 60-VF-channel supergroup signal used for terrestrial cable or microwave FDM links.

9.5 Color Television The baseband signal for television is a composite of the visual information signals and synchronization signals. The visual information is transmitted as three signal components, denoted as the Y, I, and Q signals. The Y signal is a luminance, or intensity, component and is also the only visual information signal required by monochrome receivers. The I and Q signals are termed chrominance components, and together they convey information on the hue or tint and on the amount of saturation of the coloring which is present. The synchronization signal consists of narrow pulses at the end of each line scan for horizontal synchronization and a sequence of narrower and wider pulses at the end of each field scan for vertical synchronization. Additional synchronization for the color information demodulation in the receiver is superimposed on the horizontal pulses, as described below. The luminance signal and the synchronization pulses require a base bandwidth of 4.2 MHz for North American standards. The baseband extends down to and includes a dc component. The composite signal containing the luminance and synchronization information is designed to be fully compatible with the requirements of monochrome (black-andwhite) receivers. In transmitting the chrominance information, use is made of the fact that the eye cannot resolve colors to the extent that it can resolve intensity detail; this allows the chrominance signal bandwidth to be less than that of the luminance signal. The I and Q chrominance signals are

transmitted within the luminance bandwidth by quadrature DSBSC (as seen later), modulating them onto a subcarrier which places them at the upper end of the luminance signal spectrum. Use is made of the fact that the eye cannot readily perceive the interference which results when the chrominance signals are transmitted within the luminance signal bandwidth. The baseband response is shown in Fig. 9.5. Different methods of chrominance subcarrier modulation are employed in different countries. In France, a system known as sequential couleur a m moire (SECAM) is used. In most other European countries, a system known as phase alternation line (PAL) is used. In North America, the NTSC system is used, where NTSC stands for National Television System Committee. In the NTSC system, each chrominance signal is modulated onto its subcarrier using DSBSC modulation, as described in Sec. 9.3. A single oscillator source is used so that the I and Q signal subcarriers have the same frequency, but one of the subcarriers is shifted 90 in phase to preserve the separate chrominance information in the I and Q baseband signals. This method is known as quadrature modulation (QM). The I signal is the chrominance signal which modulates the in-phase carrier. Its bandwidth in the NTSC system is restricted to 1.5 MHz, and after modulation onto the subcarrier, a single-sideband filter removes the upper sideband components more than 0.5 MHz above the carrier. This is referred to as a vestigial sideband (VSB). The modulated I signal therefore consists of the 1.5-MHz lower sideband plus the 0.5 MHz upper VSB. The Q signal is the chrominance signal which modulates the quadrature carrier. Its bandwidth is restricted to 0.5 MHz, and after modulation, a DSBSC signal results. The spectrum magnitude of the combined I and Q signals is shown in Fig. 9.5. The magnitude of the QM envelope contains the color saturation information, and the phase angle of the QM envelope contains the hue, or tint,
