Abstract
Electronic circuit technology is an important field with several scientific and practical applications. and that technology has been found that most modern electronic devices required nonlinear elements such as diodes, Transistors and operational amplifiers. Diodes have a variety of applications in electronics, including rectification, voltage demodulators, voltage regulation, logic gates and so on. In addition, transistors have many applications, which are widely used in electronics for amplification, switching, digital logic circuits, Power regulation, and oscillators. However, op-amps are electronic devices that can be used in a wide range of applications including Amplification, inverting, noninverting, summers, integrators, filtering, and comparators. This paper presents some examples of experimental simulation using Simulink software as a demonstration to students to make them understand the fundamentals of these nonlinear elements. Some experimental simulations were dealt with using diodes as a half-wave rectification, full-wave rectifier voltage regulator, and voltage limiter. However, the other experimental simulations dealt with OP-amp as an inverting, non-inverting, summer, subtractor, integrator and differentiator. Additionally, an operational amplifier is an important element in the design of active filters. Students can easily learn how to make experiment with this software in order to learn at their own time and pace. This helps visualize the fundaments of Op-Amp as well as any other physical system.
