G. Rizzoni, Principles and Applications of Electrical Engineering Problem solutions, Chapter 14 14.1 Chapter 14 Instructor Notes Chapter 14 logically follows the material on combinational digital logic circuits introduced in Chapter 13. Section 14.1 contains a discussion of sequential logic modules; the box Focus on Measurements: Digital Measurement of Angular Position and Velocity (pp. 679-681) illustrates the use of a counter to measure the speed of rotation of a slotted wheel; this is a very common measurement in mechanical systems; the box Focus on Measurements: Seven-Segment Display (pp. 682-683) draws attention to a very common logic module. Section 14.2 provides an elementary introduction to sequential logic design, and Section 14.3 introduces microcomputers. This, and the two following sections on microcomputer architecture and microcontrollers, have been extensively revised, and are designed to provide an introduction to the concept of mechatronic design (see box on p. 688), recognizing that it is impossible to include a serious coverage of microcontrollers in a single chapter. Thus, the treatment is focused on an overview of the organization of microcontrollers, including a brief, qualitative illustration of computer interface issues presented in Focus on Measurements: Reading Sensor Data By Using Interrupts (pp. 697-698). The last section, 14.6, is dedicated to an example (courtesy of Delphi – Delco Electronic Systems) that describes a current automotive engine microcontroller. The example is a qualitative description, but will permit the instructor who desires to do so to motivate further study of this topic. The Find-It-On-The-Web references will provide students and instructor with additional reference material on the subject of automotive engine control. In recent years mechanical and industrial engineering programs have seen a significant growth in courses related to mechatronics, or more specifically to microcontroller applications in industrial and mechanical systems. The objective of Chapter 14 is to serve as an introduction to such courses. The homework problems are mostly devoted to sequential logic circuits; the last 6 problems review simple concepts related to the architecture and functions of microcomputers. Learning Objectives 1. Analyze the operation of sequential logic circuits. Section 1. 2. Understand the operation of digital counters. Section 1 . 3. Design simple sequential circuits using state transition diagrams. Section 2 . 4. Study the basic architecture of microprocessors and microcomputers. Sections 3,4, 5 .
