**Course Prerequisites:** DC Principles (Block A21);
**What Students Learn: **Electronics Workbench is an electronics lab in a computer. A powerful software tool that simulates the behavior of analog circuits, digital circuits, and the corresponding test equipment. Students perform experiments faster, in a safe, user friendly environment.

Sophisticated troubleshooting options allow trainees to make practical evaluations of the theory they have been learning. High quality, visual circuit paths are recreated. The simulator lets students design, build, and verify circuits significantly faster than on a real test bench. As self-paced study, students can experiment with "what if" scenarios. Circuits can be created with any number of faults or malfunctions for students to diagnose, isolate, and repair.

Realistic test instruments used in working applications include the digital multimeter, oscilloscope, function generator, word generator, logic analyzer, logic converter, and bode plotter. A "bottomless" bin of real world components for both digital and analog circuits include over 125 74xx and 74xxx chips, resistors, diodes, capacitors, a wide variety of logic gates, scrs', triacs, npn, and pnp transistors and many more.
