Electronic Communication Techniques, Fifth Edition,is intended to bridge the gap between circuit design and the system concepts that predetermine circuit requirements in particular applications. The results of theoretical research are combined with engineering principles, design equations, charts, and tables for those of us who will design and produce hardware and software. The mathematics level is typical of that used by engineering practitioners, with calculus and transform techniques occasionally employed. Enough circuit detail and topical coverage have been included to provide material for two or even three courses in analog and digital communications technology, depending on the depth and pace desired. Use in a one-term course is also feasible, as is shown shortly. Any sequence of topics needed for a particular program may be selected. NEW TO THIS EDITION The main additions to the fifth edition, optical and cellular networks, are in Chapters 17 and 18 and include Internet basics. Dense wavelength-division multiplexing (DWDM) exploded when the International Telecommunications Union issued a grid of wavelengths for DWDM and coarse wavelength-division multiplexing (CWDM). Devices to implement DWDM, such as arrayed waveguide gratings, fiber Bragg gratings, and thin-film filters, are discussed. Digital and analog system applications of WDM, including digital transmission infrastructure for telephony with local exchange and intercarrier loops, local area networks, and digital loop carrier technology, are included. A new Internet section includes protocol basics, routers, switches, and add/drop multiplexers (electronic and optical). This transition into wide-area networks with optical switching, including multiprotocol label switching (MPLS) and generalized MPLS with all optical switching and crossconnects, is made possible by adding a label ahead of IP packet headers. Also, a new section on broadband analog DWDM updates the section on broadband RF signals on first-generation fiber optic CATV networking. Chapter 17 now includes Bluetooth technology with hardware and link connection, and packet management software aspects for personal area wireless interconnectivity among devices within a home/office environment. Also added is "Wi-Fi," an unlicensed 2.4-GHz, IEEE 802.1lb wireless local-area network (WLAN) standard with very low transmission power for short-range wireless LANs in public places such as waiting rooms, coffee shops, convention sites, and airports. Pedagogical components are improved with the addition of Chapter Previews. Also, the Abbreviations and Acronyms table has been updated. ORGANIZATION OF THIS TEXT Chapter 1 provides a review of tuned circuits and amplifiers for continuity with previous courses. There is more material on lownoise amplifiers and saturation characteristics in Chapter 7. RF oscillators (Chapter 2) are considered as stable tuned amplifiers with well-defined feedback arrangements. Oscillators also provide the carrier signal for subsequent modulation in transmitters. A section on phase noise has been included in Chapter 17. Development of the frequency domain and the signal spectra of common periodic waveforms in Chapter 3 include Fourier transforms and Fourier series analysis. Noise fundamentals in Chapter 4 include a typical treatment enhanced with circuit noise power analysis using shot and thermal noise spectral density techniques. System noise figure and temperature are included. A detailed derivation of the equation for the system noise figure is presented in Chapter 5, which also introduces communication systems and amplitude modulation. Other aspects of noise and signal-to-noise ratio are introduced in the context of their effects on analog receivers in Chapter 5 and in their statistical nature as it affects transmission error in pulsed and digital data systems in Chapter 13. The continuous information signals discuss
