  • Some basic concepts of analogue signals are introduced in this section. You will learn the basic functions of an analogue electronic system, viz. transformation and generation of signals of continuous nature. Here, signal transformation refers to all kinds of manipulation such as filtering (selecting signals of a certain range of frequencies) and amplification (enlarging the magnitude of a signal). Signal generation in the context of analogue electronics can be taken to mean the construction of a signal with a specified waveform, as in the case of a sinusoidal wave generator.

  • Control problems arise in the plant and must be solved in the plant. Until plant engineers and control designers are able to communicate with each other, their mutual problems await solution. I do not mean to imply that abstract mathematics is not capable of solving control problems, but it is striking how often the same solution can be reached by using good common sense. High-order equations and high-speed computers can be manipulated to the point where common sense is dulled

  • Nanotechnology in Biology and Medicine is intended to serve as an authoritative reference for a wide audience involved in research, teaching, learning, and practice of nanotechnology in life sciences. Nanotechnology, which involves research on and the development of materials and species at length scales between 1 to 100 nm, has been revolutionizing many important scientific fields ranging from biology to medicine. This technology, which is at the scale of the building blocks of the cell, has the potential of developing devices smaller and more efficient than anything currently available.

  • The World is confronted with a plethora of potentially disruptive technologies – some, such as nanotechnology, will inevitably challenge our cherished social, economic and industrial stability over the next two decades. Rational design and manufacture of materials properties through nanostructure control will profoundly affect the food we eat, the sources of water and power we use, our health services, our national security, housing, transportation, etc. Precisely what will be the ultimate effect of these disruptions is still unclear.

  • This book addresses the engineering student and practising engineer. It takes an engineering-oriented look at semiconductors. Semiconductors are at the focal point of vast number of technologists, resulting in great engineering, amazing products and unheard-of capital growth. The work horse here is of course silicon. Explaining how semiconductors like silicon behave, and how they can be manipulated to make microchips that work—this is the goal of our book.

  • Computers are machines designed to process, electronically, specially prepared pieces of information which are termed data. Handling or manipulating the information that has been given to the computer, in such ways as doing calculations, adding information or making comparisons is called processing. Computers are made up of millions of electronic devices capable of storing data or moving them, at enormous speeds, through complex circuits with different functions.
