Single-sideband suppressed carrier is a form of AM, but transmits only a single sideband, rather than the two sidebands and the complete carrier of amplitude modulation. In SSB the carrier, which holds no information, and the other sideband, which duplicates the information present in the transmitted sideband, are strongly attenuated (Fig. 2.16). Since one of the sidebands is attenuated, SSB requires only half the bandwidth that AM consumes for its transmissions, which also translates into less noise received (Fig. 2.17). Although amplitude modulation s fading characteristics are quite poor, in SSB fading is much less of a problem. This is because the multiple phase dependencies between all of AM s transmitted elements both sidebands and the carrier need not be sustained in SSB, inasmuch as only a single sideband is actually being transmitted. Power efficiency is also much higher in SSB than in AM because of the power savings in transmitting only a single sideband, while further power is conserved since a transmitted signal is produced only when the baseband is actually present at the modulator.

This result allows us to replace a set of resistors connected in series by a single resistor whose resistance is given by (3.1). EXAMPLE 3-1 Find the equivalent resistance seen at the two end terminals for the series circuit shown in Fig. 3-5.

Notice that to connect the nodes to the L2/L3 Network in the diagram above requires twice the amount of fiber to achieve the same connectivity as the ring. This demands twice the investment in fiber to build the metro transport network.

NOTE: Associating user configurations to groups is supported only in Active Directory domains that use Active Directory authentication. User data is always up to date because it is stored in a central location to avoid any data replication latency associated with Active Directory. You can load-balance your shares among multiple computers that can each host an NTFS network share for higher availability. Helps reduce the authentication task workload from your Active Directory environment. When using the NTFS file share for a Central Store, consider the
