  • Today’s control system designers face an ever-increasing “need for speed” and accuracy in their system measurements and computations. New design approaches using microcontrollers and DSP are emerging, and designers must understand these new approaches, the tools available, and how best to apply them. This practical text covers the latest techniques in microcontroller-based control system design, making use of the popular MSP430 microcontroller from Texas Instruments.

  • • Analog voice data must be translated into a series of binary digits before they can be transmitted in digital transmission system. One means of doing this is called pulse amplitude modulation (PAM). • The process of converting analog signal to digital is also known as A_to_D conversion or A/D conversion. The circuit does the conversion known as A/D converter. In analog modulation (continuous wave modulation), some parameter of a sinusoidal carrier wave is varied continuously in accordance with the message signal. ...

  • Communication systems consist of an input device, transmitter, transmission medium, receiver and output device, as shown in Fig. 1.1. The input device may be a computer, sensor or oscillator, depending on the application of the system, while the output device could be a speaker or computer. Irrespective of whether a data communications or telecommunications system is used, these elements are necessary.

  • In almost all areas of daily life the demands on the communications infrastructure increased dramatically. With regard to the volume of data that has to be transmitted, no matter whether we are dealing with public or private networks, industrial fields or automobiles, needs will continue to rise. Consequently, the demands on the bandwidth of communications systems will continue to increase since more and more video data streams with high picture quality (IP TV), in addition to telephone and data circuits, will be transmitted.

  • Today’s transmission methods and equipment are robust and reliable and feature integrated network monitoring, troubleshooting, maintenance, and provisioning systems. However, public carriers and most major private networks have historically engineered their network’s physical plant to include access points at which they can gain quick and organized “hard-contact” access to any particular circuit path. Typically, these access points were comprised of analog jackfields with “line-drop-monitor” access capability.

  • Most antenna engineers are likely to believe that antennas are one technology that is more or less impervious to the rapidly advancing semiconductor industry. However, as demonstrated in this lecture, there is a way to incorporate active components into an antenna and transform it into a new kind of radiating structure that can take advantage of the latest advances in analog circuit design

  • Telephone networks use circuit switching. The telephone network had its beginnings in the late 1800s. The entire network, which is referred to as the plain old telephone system (POTS), was originally an analog system using analog signals to transmit voice.

  • Synchronous Mode Synchronous systems negotiate the connection at the data-link level before communication begins Basic synchronous systems will begins. synchronize two clocks before transmission. Asynchronous mode Asynchronous systems do not send separate information to indicate the encoding or clocking information. The receiver must decide the clocking of the signal on it's own. This means that the receiver must decide where to look in the signal stream to find ones and zeroes.

  • This book is intended to bridge the gap between formal engineering texts and more popularly accessible descriptions of electric power technology. I discovered this gap as a graduate student struggling to understand power systems—especially transmission and distribution systems—which had always fascinated me but which now invited serious study in the context of research on implementing solar energy. Although I had studied physics as an undergraduate, I found the subject of power systems difficult and intimidating....

  • I enjoyed reading this book for a number of reasons. One reason is that it addresses high-speed analog design in the context of microwave issues. This is an advanced level book, which should follow courses in basic circuits and transmission lines. Most analog integrated circuit designers in the past worked on applications at a low enough frequency that microwave issues did not arise. As a consequence, they were adept at lumped parameter circuits and often not comfortable with circuits where waves travel in space.

  • The passive components used in electronic circuits all make use of one or more of the three fundamental phenomena of resistance, capacitance and inductance. Some components depend for their operation on the interaction between one of these electrical properties and a mechanical property, e.g. crystals used as frequency standards, piezo-electric sounders, etc. The following sections look at components particularly in the light of their suitability for use at RFs, and at how they can be inter-connected for various purposes....

  • The dramatic reduction in transmission loss of optical fibers coupled with very important developments in the area of light sources and detectors have resulted in phenomenal growth of the fiber optic industry during the last 35 years or so. Indeed, the birth of optical fiber communication systems coincided with the fabrication of low-loss optical fibers and the operation of room-temperature semiconductor lasers in 1970. Since then, scientific and technological growth in this field has been phenomenal.

  • Electromagnetism is fundamental to the whole of electrical and electronic engineering. It provides the basis for understanding the uses of electricity and for the design of the whole spectrum of devices from the largest turbo-alternators to the smallest microcircuits. This subject is a vital part of the education of electronic engineers. Without it they are limited to understanding electronic circuits in terms of the idealizations of circuit theory.
