TweetThis post is about amplifiers, how they work, and common applications. I will cover several operational amplifier configurations, and situations where each might be useful. This is part I of II for general discussion about amplifiers. Enjoy! Definition of an amplifier Definition (for Bioinstrumentation): Circuit that makes a small signal, usually voltage but occasionally current [...]

TweetThe 3 common methods of describing a point in a three dimensional coordinate system are Cartesian, Cylindrical and Spherical. The most simple is Cartesian but certain teachers find it necessary to use the others. There are a few simple conversions between them but first it is necessary to know their notation. Cartesian: Cylindrical: Spherical: In [...]

TweetSuppose you are interested in finding the unit vector between two points, and , which are described in cartesian coordinates as and , respectively. You would begin by finding the vector between these two points. The direction of this vector may be important so look for key words such as . Once we have established [...]

TweetWhat is the Laplace Transform method? The Laplace Transform is a method that simplifies integral and differential equations into algebraic equations. This practice is commonly used to solve for a function out of a differential equation, which otherwise may have been unsolvable or very difficult. The following integrals can be used to transform between where [...]

TweetI have already put a lot of material up related to inductors and capacitors, but more can’t hurt anyone. I have a few new things to say about the inductor and the capacitor and a few different graphical approaches to common problems you will encounter in your electrical engineering classes. /quick review Inductors Units of [...]
