This book is designed for all students of engineering, arts and science colleges of various universities in India. An easy to understand text with crisp but complete explanation of topics will enable the students to understand the basic concepts easily.

The digital electronics refer to devices and circuits that process digital signals which are coded in binary. The real world signals are analog and hence the field of electronics was dominated by analog devices and circuits before the invention of digital devices. The real world analog signals are converted to digital signals and processed by digital systems and after processing the digital signals are used either directly or converted back to analog for real world applications. The ADCs (Analog-to-Digital Converters) are used for converting analog signals to digital signals and DACs (Digital-to-Analog Converters) are used to convert digital signals to analog signals.

This book is organized with 15 chapters. The fundamental concepts, analysis and design of digital systems are presented in a very easiest and elaborative manner. Throughout the book, carefully chosen examples are presented so that the reader will have a clear understanding of the concepts discussed.

• Chapter 1 provides a simple introduction to various aspects of digital system. Chapter 2 starts with a discussion of various number systems and basic arithmetic operations in these number systems. Representation of negative numbers by complement numbers and arithmetic in complement number systems are also presented in this chapter with examples.
• Chapter 3 is devoted to various types of binary codes. BCD codes, alphanumeric codes and error detection and correction codes are clearly explained with appropriate examples. Addition and subtraction in excess-3 code is also explained with examples.
• Chapter 4 includes Boolean algebra and theorems, Boolean functions and basic concepts of logic gates. The standard forms of Boolean functions are also presented in this chapter. Implementation of Boolean functions using universal gates and standard logic gate ICs are also discussed in this chapter.
• Boolean function minimization using theorems, K-maps and Quine-McCluskey methods are discussed in Chapter 5. The formation of prime implicants using 1’s and 0’s are clearly explained with examples.
• Chapter 6 is devoted to combinational logic circuit analysis and design. The analysis and design of code converters, decoders, encoders, multiplexers and de-multiplexers are presented with clear examples. Implementation of combinational logic circuits using multiplexers, decoders and standard ICs are also discussed in this chapter. Some application examples of combinational logic systems like digital trans-receiver, Parity generator and checker and BCD to 7-Segment decoder are included in this chapter.
...
• A brief discussion on various types of semiconductor memory and programmable logic devices are presented in Chapter 14. The digital system design using programmable ICs like PROM, PLA and PAL are explained with appropriate examples. A short note on advanced programmable ICs CPLD and FPGA are also included in this chapter.
• Basic concepts of DAC and ADC are discussed in Chapter 15. Some popular types of DAC and ADC are explained clearly with appropriate diagrams. The standard and commonly used digital ICs are listed in Appendix for ready reference to implement digital systems using standard ICs.
