Description : 110 Waveform Generator Projects for the Home Constructor deals with waveform generator circuits that can produce forms of sine, square, triangle, sawtooth, ramp, pulse, or staircase. The generator circuits, built by the constructor using transistors, operational amplifiers or digital integrated circuits, can produce modulated or unmodulated outputs, with single or multiple form outputs. The constructor must follow two requirements in building a simple sine-wave oscillator: firstly, the output of an amplifying device must be fed back to its input via a frequency-selective network in such a way that the sum of the amplifier and feedback network phase-shifts equals zero (or 360) degrees at the desired oscillation frequency. Secondly, the gain of the amplifying device must exactly counter the loss or attenuation of the frequency-selective feedback network at the desired oscillation frequency, to give an overall system gain of precise unity. The book also describes different waveform modulations, such as amplitude modulation (a.m.), frequency modulation (f.m.), frequency-shift keying (f.s.k.), phase-shift keying (p.s.k.), sweep modulation, carrier keying, and how to apply these in practical circuits. Radio technicians, engineers, apprentices, hobbyists, and students of electrical engineering or electronics will find the book very useful.

Description : 110 Semiconductor Projects for the Home Constructor describes practical circuits, simple amplifiers, relay driving circuits, electronic switches operated by light or by sound, amplifiers with high input impedances, voltage regulators, and a constant-volume amplifier. Other circuits include wave-form generators, analogue-to-digital converters, logic circuits, frequency dividers, a d.c. chopper, and power controller circuits. The book describes the characteristics of the 2N29s6 npn manufactured by G.E.C. and the 2N3702 pnp where, in conjunction with a Schmitt trigger or a voltage operated electronic switch, these transistors can be used in voltage regulator circuits, light operated switches, or timer switches. The text also discusses the junction-gate field-effect transistors which can be used as amplifiers, or when used in conjunction with ordinary transistors, give superb performance in hybrid circuits. Field-effect transistors can also be used in timer circuits or in constant-volume amplifiers. The book explores the unijunction transistor that can be used in wide-range pulse generators, wide-range saw-tooth generator, analogue/digital converter, as well as a variable on/off-time lamp flasher. In high power switching projects, the silicon controlled-rectifier, also known as a thyristor, can be used. The book is suitable for radio technicians, engineers, apprentices, and students of electrical engineering or electronics.

Description : 110 Integrated Circuit Projects for the Home Constructor, Second Edition (Completely Revised) describes five types of linear integrated circuits and 110 projects in which these can be utilized. The book describes the typical characteristics of the 741 op-amp (with open-loop voltage gain, input impedance) and the variety of ways where it can be used in basic linear amplifier applications. The type 555 timer is designed for precision timing applications, monostable multivibrator, astable multivibrator, and Schmitt trigger applications. The XR-2206 i.c. can be used by the technician as a simple waveform generator or as a complex function generator with a variety of modulation facilities. The LM380 i.c. is an easy-to use general-purpose power audio amplifier. The technician can use it as simple non-inverting 2W amplifier, or in conjunction with a single bipolar transistor, as a small baby alarm. The 723 voltage regulator i.c. can be used in a variety of fixed or variable voltage power supply applications. It can be used as a low voltage (2-7.2V) regulator and, if the technician modifies the circuit, it can produce variable output voltages. The book is suitable for engineers, apprentices, technicians, and students of electrical engineering or electronics.

Description : The audio amplifier is at the heart of audio design. Its performance determines largely the performance of any audio system. John Linsley Hood is widely regarded as the finest audio designer around, and pioneered design in the post-valve era. His mastery of audio technology extends from valves to the latest techniques. This is John Linsley Hood's greatest work yet, describing the milestones that have marked the development of audio amplifiers since the earliest days to the latest systems. Including classic amps with valves at their heart and exciting new designs using the latest components, this book is the complete world guide to audio amp design. John Linsley Hood is responsible for numerous amplifier designs that have led the way to better sound, and has also kept up a commentary on developments in audio in magazines such as The Gramophone, Electronics in Action and Electronics and Wireless World. He is also the author of The Art of Linear Electronics and Audio Electronics published by Newnes. Complete world guide to audio amp design written by world famous author Covers classic amps to new designs using latest components Includes the best of valves as well as best of transistors

Description : In a remarkably short time, electronics has penetrated almost every aspect of modern life and the pace of development in the field shows no sign of slackening. One of the first books to cover electronic inventions in depth, Electronic Inventions and Discoveries: Electronics from Its Earliest Beginnings to the Present Day, Fourth Edition traces the development of electronics from its earliest beginnings to the present day. Spanning a period of two and a half centuries, the book presents a mini-encyclopedia full of valuable information on practically all inventions in electronics from 1745 to 1996. This fourth edition has been brought up-to-date and made more attractive by a complete redesign while still maintaining the successful features of previous editions. The first nine chapters supply concise yet comprehensive histories of the main areas of the subject. Subsequent chapters provide a list of inventions by subject and succinct descriptions of each invention in date order with over 1,000 references. The book concludes with a list of acronyms and abbreviations, a list of books on inventions and inventors, and a comprehensive index. During his seventy years in the field, the author has collected a variety of published data to form an up-to-date systematic review of the major developments in electronics and the pattern of advances in electronic techniques. The book forms an essential source of reference to practicing engineers wishing to broaden their knowledge. Teachers and students who require a sound background and understanding of electronics will also find the book invaluable. Written in an easily understood largely nontechnical language, this fascinating and authoritative history of electronic developments will be of great interest to electronic hobbyists and general science readers.
