Coaxial cable is less sensitive to noise and is suited for higher transmission speeds than twisted-pair cable. Baseband techniques (serial bit-by-bit transmission) as well as (frequency modulated) broadband techniques are possible. Types of possible communication techniques in coaxial cables are listed in Table 9.2. 

To compensate for a broad range of coupling constants encountered within one sample, Wimperis and Bodenhausen115 developed Broadband-INEPT which includes six more pulses and four more delays, but the need for broadband-INEPT has apparently not yet been sufficiently felt in 29Si NMR just as better refocusing of INEPT CR116 went unnoticed in the organosilicon community.

A state-of-the-art description of broadband ultrafast infrared pulse generation and multichannel CCD and IR focal plane detection methods has been given in this chapter. A few poignant examples of how these techniques can be used to extract molecular vibrational energy transfer rates, photochemical reaction and electron transfer mechanisms, and to control vibrational excitation in complex systems were also described. The author hopes that more advanced measurements of chemical, material, and biochemical systems will be made with higher time and spectral resolution using multichannel infrared detectors as they become available to the scientific research community. 

Connecting terminals to hosts appears to be the most widely used area for broadband. Allows the same channel to carry voice and video signals. The signal rates for broadband are not impressive for data communications at this time under 1 million bits per second for most applications ...

An accelerating trend for today s cell phones is to support multi-mode, multi-standard, and multi-band operations, which require even more complex RF front-end circuits. Meanwhile, the communication-oriented cell phone standards are converging with wireless broadband access standards WiFi1 61 and WiMax (806.16d/e)1171. Wireless terminals are expected to be able to deliver computing, computation, and entertainment functionalities virtually anytime, anywhere. As a result, a large variety of heterogeneous functionalities could be found on the... 

Quarter-wave interference films have seen numerous uses in the field of optical security, due to the strength of reflection and the ability to select numerous colors, and in particular for their observable color shift. Decorative nanolayer quarter-wave polymeric material with more than 100 layers have been known for twenty years, but was not used in the security sector because of their weak iridescent appearance. The 3 M Corporation uses PEN to manufacture reflectors with good band-edge control which are extremely efficient broadband mirrors for communication. These devices are easily noticed by the typical observer and are machine-readable. The PEN quarter-wave mirror films may be fine-line embossed and thinly layered which enliances their appearance [76]. 

These are, in alphabetical order, ash-free filters, bandpass filters, black band filters, blue band filters, broadband filters, cigarette filter, fluted filters, high-pass filters, low-pass filters, qualitative filters, and quantitative filters. The filter is catholic. In German, in chemistry the filter has neutral gender. In communication theory, the filter has male gender, however. 

Fig. 6. Pulse sequence for the refocused- or D-HMBC experiment. The idea of refocusing anti-phase proton single quantum coherence prior to acquisition to allow broadband heteronuclear decoupling during acquisition was first reported by Bermel et al in 1989. Evidently unaware of the initial report, Furihata and Seto again de.scribed this experiment in a 199.5 communication, giving it the acronym D-HMBC. There have been a number of applications of this experiment for the acquisition of both H- Cand long-range...

Advances in communication capability (e.g., broadband) result in a much faster information flow, and decisions and actions are expected in a short time. 

Centralized methods of sensor networking make impractical demands on cable installations and network bandwidth. The burden on commnnication system components, networks, and human resources can be drastically rednced if raw data are processed at the source and the decisions conveyed. The same holds true for systems with relatively thin communications pipes between a source and the end network or systems with large numbers of devices. The physical world generates an nnlimited quantity of data that can be observed, monitored, and controlled, bnt wireless telecommunications infrastructure are finite. Thus, even as mobile broadband services become available, processing of... 

It was pointed out in Chapter 2 that arrays possess unique features from a radar cross section point of view. To reduce the RCS outside the operating band of an antenna in general, a bandpass radome is often placed in front of it (see Chapter 2, Fig. 2.1). In the case of an array we recall from Chapter 2 that a low RCS is obtained when the terminal reflection coefficient is low in other words, the bandwidth of the array should ideally exceed that of the radome. Furthermore, due to the high price tag of arrays in general, it is desirable to pass on as much information through them as possible. Thus, we shall in this chapter consider the principles for broadband arrays, which is of interest to the communication community. 

Operational communications States and territories continue to develop state emergency communications plans. In addition, the nation began facilitating a transition to a nationwide public safety broadband system for emergency communications and continued development of next generation 9-1-1 systems. 

A major emerging application of optical fibers is in the distritoion of radio signals for broadband services and wireless communication systems fiber can provide a low loss backbone with large bandwidth. Snch systems require optical sources with narrow linewidth, low noise, and moderate output power. Externally modulated single mode fiber lasers are therefore well suited to applications in these systems. Dual wavelength fiber lasers (e.g., dual polarization mode DFB lasers) are also potentially useful for the generation of millimeter wave radio carriers.
