Several controllers are presented, such as a manual starter, magnetic overload relay, pneumatic timing
relay, bimetallic thermal overload relay, drum switch, electronic drive, and programmable controller.
Chapter 5 covers troubleshooting of residential and industrial wiring. The basic theory and
fundamentals of wiring are explained, followed by troubleshooting of such circuits as distribution
panels, three-way and four-way switching controls, wye and delta wiring, polyphase industrial wiring,
fiber optics, and television and antenna distribution systems.
Chapter 6 covers the troubleshooting of radio and television. It begins by describing the theory
and component stages of AM, FM, FM multiplex, and HD, UHD, and smart television circuitry. This
chapter then presents the typical problems encountered, along with methods for testing and repairing
these products.
Chapter 7 is an introduction to digital systems and troubleshooting. Topics include analog and
digital circuits, basic logic gates, digital technologies, safety, open and short digital circuits,
troubleshooting examples, and troubleshooting equipment such as oscilloscopes, logic analyzers, logic
pulsers, and logic probes.
Chapter 8 explains the building blocks of modern combinational and sequential circuits. It starts
with flip-flops, decoders, and encoders. Next, it covers shift registers, counters, and digital-to-analog
and analog-to-digital converters that are constructed from flip-flops. Troubleshooting synchronous
logic is covered as well.
Chapter 9 introduces microprocessors, microprocessor-based systems, and troubleshooting.
Memory, input/output, troubleshooting microprocessor-based systems using in-circuit emulator (ICE),
microprocessor chips such as Intel’s LGA2011 and Zilog’s Z-80180, memory upgrade, and
disassembled and decompiled memory dumps are the major topics covered in this chapter.
Chapter 10 presents the cutting-edge technology of biomedical equipment and troubleshooting.
Electrical safety is emphasized. Biomedical engineering technology concepts related to equipment
such as defibrillators, and ECG, EEG, hemodialysis, MRI, ultrasound, and X-ray machines; and
troubleshooting, and preventive maintenance are introduced.
Chapter 11 provides a modern overview of computer networking. Topics include configuring
network devices such as routers and switches using Cisco IOS commands, IP addressing, subnetting,
virtual local area networks, network troubleshooting through OSI layers, a network troubleshooting
example using a flowchart, and a troubleshooting example for routers.
Chapter 12 covers the exciting field of embedded microprocessor systems. Embedded systems
are explained briefly, followed by the troubleshooting of microcontroller-based systems; timing
diagrams for microprocessor and microcontroller; Zilog’s Z16FMC microcontroller; recurrent-sweep
and triggered-sweep oscilloscopes; logic analyzers; programmable devices such as PALs, CPLDs,
FPGAs, and FPLAs; and Raspberry Pi.
The authors believe that this book will be valuable and insightful to you in advancing your or
your students’ knowledge and skills in the exciting and important field of electrical and electronic
troubleshooting.
