Figure 5.1 Analog system performance measurements can be made either at the local loop access voice band frequencies using a Transmission Impairment Measuring Set (TIMS), usually at the 4-wire 600-ohm line, or at the Frequency Division Multiplex (FDM) line level using a Selective Level Measuring Set (SLMS). At the multiplex level the frequencies are much higher, typically starting at 60 kHz and going up to 65 MHz. A range of analog transmission measurements can be made with both test sets, as shown in this diagram.

DLCIs are locally signi cant: Your router uses a local DLCI number in the frame relay frame header to indicate the destination peer to which

where IP receiver s total IP3 from its input to its output and IP3n and TOT GAINn are linear terms, not decibels. 4. The importance of a low NF in a receiver is demonstrated by its linear relationship with SNR. For instance, if a receiver has an NF of 12 dB, and the SNR at its output is 20 dB, we can improve the SNR to 30 dB (using the same input signal power and receiver gain) by decreasing the receiver s NF to 2 dB. This is a 10-dB improvement in NF and in SNR. Thus, if a certain signal power is placed at the input of a 5-dB NF receiver, and this creates an output with an SNR of 20 dB, then the actual input SNR to the receiver will have been 25 dB. In other words, the receiver added 5 dB to the noise at its output: the receiver s NF directly correlated into a decrease in the output signal s SNR. This also affects the power that the transmitter must send to the receiver s antenna to make up for the decreased SNR caused by a receiver s poor NF, with a relationship that is also dB for dB. The NF for a receiver can be calculated by using Friis s equation, with the noise figure itself not needing to be referenced to any particular bandwidth, since it is a ratio between the input and the output of a receiver (or amplifier) over exactly the same bandwidth: NFTOTAL 10 log (10NF1/10) (10NF2/10) 1 (10G1/10) (10NF3/10) 1 (10G1/10) (10G2/10) (10NFn/10) 1 (10 ) (10G2/10) (10Gn/10)

Strength I limit state: SF at girder ends: Compute VDC DW Compute VLL IM Girder web DW, tw: Required end panel transverse stiffener spacing for stiffened girders 1.5 D. Shear resistance of end panel: Maximum shear forces: Maximum shear force at supports for variety of loads (non-symmetric axle lane) Results of a simpli ed analysis approach can be presented in a summary of tables. The comparative study would help in frequently used design and rating for moments and forces.

Although the use of ASCII coding in SDP, as opposed to binary coding, is a little bandwidth greedy, SDP is written in a compact form to counteract bandwidth inefficiency. Thus, where English words might have been used for field names, single characters are used instead. For example, v is version, s is session name, and b is bandwidth information.

Hybrid codecs attempt to fill the gap between waveform and source codecs. As described previously, waveform coders are capable of providing goodquality speech at higher bit rates. They can even provide relatively acceptable quality at rates down to about 16 Kbps. They are of limited use at lower rates, however. Vocoders, on the other hand, can provide intelligible speech at 2.4 Kbps and lower, but they cannot provide natural-sounding speech at any bit rate. The objective with hybrid coders is to provide goodquality speech at a lower bit rate than is possible with waveform coders. Although other forms of hybrid codecs exist, the most successful and most commonly used are time domain Analysis-by-Synthesis (AbS) codecs. Such codecs use the same linear prediction filter model of the vocal tract as found in Linear Predictive Coding (LPC) vocoders. Instead of applying a simple two-state, voiced/unvoiced model to find the necessary input to this

In max-min problems the defining equation is a mathematical statement of the problem. In related rate problems the defining equation is X sometimes a little more obscure, actually Fig. 6-1 sometimes a lot more obscure! Look at the ladder in the graphic and think of a way to relate x to y. Don't start by trying to write the &/dt and dy/dt . The rates come out of the differentiation. The hard part of the problem is to see, and then write down, a relationship between the variables. Writing the defining equation that ties x and y together is the key step in the problem. In this problem the Pythagorean theorem for a right triangle relates x and y.

Figure 5.21 shows the bond-and-protect principle. Every underwater mass is connected to the boat s bonding system. To protect against stray currents outside of the hull, sacri cial anodes are connected to the bonding system and placed where they may best protect all underwater masses.
