Video Lectures created by Tim Fiegenbaum at North Seattle Community College.

We're going to be wrapping up chapter one by talking about circuit simulation. And we will be using circuit simulation throughout the course to simulate component behavior and to use it to measure circuits and to evaluate them. First of all what is circuit simulation? It is a technique where computer software simulates the behavior of an electronic circuit or system. New designs can be tested, evaluated and diagnosed without actually constructing the circuit or system. Circuit simulation may be useful tool in troubleshooting a system to gather data before circuit level troubleshooting actually takes place.

 

Virtual Instruments

Circuit simulation utilizes something called virtual instruments, and what are virtual instruments? They allow you to connect various types of test equipment to circuit without actually having to have those instruments at hand. And the types of virtual instruments available include voltmeters, ohmmeters, oscilloscopes, logic analyzers, spectrum analyzers and actually many others. And we're going to be jumping over the simulation software that we'll be using and I have a prepared screen to look at this. It is taking a few moments for this to display, just because I have many things running on this computer, and it slows it down. You'll see here we have a circuit here and we many different types of instruments that we can use to evaluate- we have a multimeter, a function generator, an ohscope and down here we have a bode plotter. And all of these devices are test equipment and they can be used in the evaluation of circuits and we will be using this software throughout this course
