Abstract
A nonlinear circuit element called a memristor has become a popular research area today. Circuits that mimic the behavior of a memristor are called memristor emulators. There are many different types of memristor emulators made. There are also optoelectronic memristor emulators in the literature, albeit in small numbers. In this study, a microcontroller-controlled memristor emulator with a hand-made optocoupler was designed. The circuit is made using an inexpensive microcontroller, the STM32F103RB microcontroller. The emulator made was used in the design of an LP filter with an adjustable cutoff frequency of low and high pass. The operation of the emulator and the filter has been studied experimentally. Experimental results show that the emulator and the LP filter circuits perform well.
期刊介绍：
Transactions of Electrical Engineering is to foster the growth of scientific research in all branches of electrical engineering and its related grounds and to provide a medium by means of which the fruits of these researches may be brought to the attentionof the world’s scientific communities.
The journal has the focus on the frontier topics in the theoretical, mathematical, numerical, experimental and scientific developments in electrical engineering as well
as applications of established techniques to new domains in various electical engineering disciplines such as:
Bio electric, Bio mechanics, Bio instrument, Microwaves, Wave Propagation, Communication Theory, Channel Estimation, radar & sonar system, Signal Processing, image processing, Artificial Neural Networks, Data Mining and Machine Learning, Fuzzy Logic and Systems, Fuzzy Control, Optimal & Robust ControlNavigation & Estimation Theory, Power Electronics & Drives, Power Generation & Management The editors will welcome papers from all professors and researchers from universities, research centers,
organizations, companies and industries from all over the world in the hope that this will advance the scientific standards of the journal and provide a channel of communication between Iranian Scholars and their colleague in other parts of the world.
