Let function s : D [??] [Z.sub.+] define the number of sessions that correspond to the demand, function r : D [??] [R.sub.+] define the nominal packet rate of a single session, and function l : D [??] [R.sub.+] define the average packet length for the demand (it can be noticed that b(d) = r(d)l(d) is the nominal bandwidth required by a single session and h(d) = r(d)l(d)s(d) is the volume of demand d [member of] D).
This is due to the fact that as the frequency shifted to the left the nominal bandwidth is not conserved anymore.
Required electric characteristics of the MTMDL are: characteristic impedance [Z.sub.0] and its tolerance [[delta].sub.Z], nominal delay time at low frequency [t.sub.dLF] and its tolerance [[delta].sub.t], nominal bandwidth [DELTA]F and its tolerance [[delta].sub.[DELTA]F].
The nominal bandwidth, set by the exit slits, is 0.6 nm.
The instrument has a nominal bandwidth of 0.7 nm and typically scans from 280 um to 600 nm in 0.2 nm steps, taking approximately 16 minutes to complete a scan.
The limit is specified out to 2.5 times the nominal bandwidth of 56 MHz, that is, 140 MHz from the nominal carrier, where another emission specification takes precedence.
Most importantly, Ethernet now offers nominal bandwidth at the same gigabit speed as Fibre Channel, with more aggressive plans to increase it over the next few years.
This activity creates a very high CPU overhead on participating computers, creates inordinate LAN congestion, and drive down throughput to a fraction of nominal bandwidth. These severe limitations still allow high-level, low traffic data access activities such as network-attached storage, but condemn using TCP/IP for storage I/O.
This antenna operates over a nominal bandwidth of 50 MHz to 4 GHz, an impressive 80:1 ratio.
The high impedance probe has a nominal bandwidth of 12.5 GHz and a dynamic range of 40 dB for nonlinear network analysis up to 40 GHz.
