For courses in Digital Electronics and Digital Logic. Created to provide a safer and more cost effective lab environment, these innovative manuals introduce new methods to learning and understanding circuit analysis concepts by using Electronics Workbench to simulate actual lab experiments on the computer. Using the latest circuit simulation software, they allow for easy circuit modification, more extensive troubleshooting experiments, and more powerful computational tools. Students work with circuits drawn on the computer screen and with simulated instruments that act like actual laboratory instruments. Circuits can be modified easily with on-screen editing, and analysis results provide fast, accurate feedback. The manuals provide extensive technical preparation for each interactive experiment, and a series of questions about the results of each experiment requires students to think about and to analyze the results of the experiments in more depth than is customary in other lab manuals. The computer simulations provide a more cost effective, safer, and more thorough and efficient approach to circuit analysis than using hardwired experiments; however, the experiments include Materials Lists and Circuit Diagrams so that they may be done either with computer simulations or in a hardwired laboratory. The lab manuals can be used with any DC/AC, Digital Electronics, or Electric Circuits texts.* Simulations of hardwired circuits and instruments - Simulates both hardwired lab experiments on the computer using circuits drawn on the screen and instruments that act like actual laboratory instruments. Allows circuit component faults to be introduced without damaging or destroying actual lab components, thus allowing more extensive troubleshooting experiments to be performed. Faulty components can be deliberately introduced in a computer simulated circuit to make it easier to find the faulty components in an actual circuit. * Use of Electronics Workbench - Similar to a workbench in a real laboratory environment - except that circuits are simulated on a computer and the results are obtained more quickly. Electronics Workbench includes a central workspace, a parts bin, and instruments stored on a shelf above the central workspace. A mouse is used to build the circuit in the central workspace, attach simulated test instruments, and run the simulation to display the results on the instruments chosen. The simulator automatically runs the proper simulation based on the particular instruments connected to the circuit. * Highly interactive experiments - Involving a wide range of difficulty. * The interactive nature of the experiments encourages student participation which leads to more effective learning and a longer retention of the theoretical concepts, and the range of difficulty continually challenges them as they acquire new knowledge and develop new skills. * Provision for hardwired lab environments - Contains experiments (complete with a circuit diagram and parts list) that can be used in a hardwired lab environment in addition to the computer simulations. * Allows the manual to be easily applied in a hardwired lab environment, and enables students to compare the computer simulated results with hardwired circuit results, which is not possible with most lab manuals. * An accompanying CD-ROM - Contains all of the troubleshooting circuits and all of the circuits needed to perform the experiments in Electronics Workbench. * Enables students to wire the circuits on the computer screen, using the components from the parts bin. By wiring the circuits in the Electronics Workbench workspace, they can create a hardwired laboratory environment. * List of Objectives. * Preparation section - Provides all of the theory and data needed to complete the procedure. * Makes it easier for students to do the calculations and answer the questions without referring to another textbook, and makes it possible for them to use the manual as a combination text and lab manual, if desired. * Materials list and circuit diagrams. * Makes it possible to use this manual in a hardwired laboratory environment. * Procedure section - Requires students to record measured data, calculate expected values, and answer a series of thought-provoking questions designed to reinforce the theory behind each experiment. * The questions in the Procedure require students to think about the results during each procedure step while the results are fresh in their minds, rather than after the entire experiment is completed. * Troubleshooting problems - At the end of each experiment. Focuses on circuit faults. In each troubleshooting problem, the parts bin has been removed to force students to find the fault by making a series of circuit measurements rather than by replacing components. (A Solutions Manual showing measured data, answers to the questions, and answers to the troubleshooting problems is available.) * Helps students develop troubleshooting skills. Using a circuit simulator makes it possible to introduce circuit faults without damaging or destroying actual components, which is not possible in a hardwired lab.
