Become familiar with engineering numbers and notation, and learn about the two most important electrical quantities: current and voltage. Getting started Circuit analysis 0 of 93 complete Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a circuit. Circuit elements Resistor circuits DC circuit analysis Natural and forced response AC circuit analysis Amplifiers 0 of 7 complete Amplifiers make signals bigger. Amplification is often the most basic operation of an electronic circuit. There are many kinds of amplifier designs. We will describe the operational amplifier, the building block of most analog electronics. Operational amplifier Semiconductor devices 0 of 3 complete Diode Electrostatics 0 of 10 complete Electrostatics is the study of forces between charges, as described by Coulomb's Law. We develop the concept of an electric field surrounding charges. We work through examples of the electric field near a line, and near a plane, and develop formal definitions of both *electric potential* and *voltage*. Electric force and electric field Fields, potential, and voltage Signals and systems 0 of 10 complete Signals and Systems covers analog and digital signal processing, ideas at the heart of modern communication and measurement. We present the basic concepts for continuous-time and discrete-time signals in the time and frequency domains. Time and frequency are related by the Fourier transform.
