“…Diantara sekian banyak simulator dalam topik persinyalan, termasuk rangkaian Filter, salah satu yang menarik untuk dieksplorasi dan perlu dilakukan pendalaman adalah Circuit Wizard karena menyediakan tampilan antarmuka yang impresif, seperti fitur yang membantu perancang agar dapat melihat arah arus listrik dalam rangkaian tertutup (pada mode circuit) dan memvisualisasikan rangkaian dengan tampilan sesuai fisik aslinya (pada mode virtual lab). Beberapa penelitian yang menggunkaan Circuit Wizard dalam mode virtual lab yaitu (Dewi et al, 2021;Fuada & Dewi, 2023) yang mensimulasikan rangkaian Timer IC NE555. Penelitian tersebut menggunakan Oscilloscope virtual untuk mengukur frekuensi output dari rangkaian Astable Multivibrator berbasis timer NE555 dan hasilnya adalah identik dengan perhitungan secara teoretis.…”

An electronic circuit that functions to block or hold signals with intermediate frequencies (median) and will forward signals between low frequencies and high frequencies is the definition of a Notch Filter. The Band Stop Filter, also often referred to as the Notch Filter, is a combination of a Low Pass Filter and a High Pass Filter connected in parallel. This connection differs from the Band Pass Filter, which connects the Low Pass Filter and High Pass Filter in series. This study aims to discuss the simulation of the Sallen-key notch filter Circuit. The author also conducts real simulations to prove the Circuit by changing or adjusting the value of the components installed in the Circuit so that the frequency response is according to the target. The purpose and role of the Sallen-key notch filter and the working principle of the theory of each filter used. The research method used in the research work is to carry out virtual simulations using virtual simulators and live simulations

“…Selain itu, setiap komponen mudah ditemukan pada setiap library yang ada. Aplikasi ini hanya dapat dilakukan secara offline sehingga tidak membutuhkan akses internet (Darmawan & Rijanto, 2019;Dewi et al, 2021;Nugroho et al, 2021). Simulator ini memuat dua mode yang berbeda, yaitu circuit dan virtual.…”

This paper reveals the voltage divider circuit to better understand the fundamental working principles in detail. The approach was simulated using popular offline simulators (i.e., Pr, CW circuit, and virtual mode, EWB, Mu, P, Ye, TS, QUCS, LTS, SI, and PhET). Two scenarios were carried out: measuring the output voltage (Vout) with known R1, R2, and DC source (Battery) as a voltage input (Vin), then looking for R1 and R2 using four different calculation methods to obtain Vout as expected. Afterward, the value of R1 and R2 were inserted into the simulation circuit to guarantee if the current Vout value matched the initial Vout. Finally, the simulation results were compared with the calculation results. All simulators provide an attractive GUI, capable of simulating voltage measurements with 100% accuracy in terms of DC analyses, which is DC voltage (except the CW software, which is only 98%), and can be entered in any resistor value (except Ye and PhET software). Surprisingly, the results of this study can provide insight for beginners to understand essential topics in electrical engineering studies, e.g., the circuit topology, fundamental theory, and working principle of a voltage divider circuit. Besides, the student will understand an offline electronic-based simulator suitable for measuring voltage parameters. Furthermore, they are expected to apply this circuit to various electronic circuit cases.

This research develops a phase-shift RC Oscillator trainer kit that can be used to give undergraduate students an understanding of one of the materials related to analog circuit practicum. The Oscillator is one of the essential subtopics to be examined thoroughly by electrical engineering students. Furthermore, the Resistor and Capacitor modules were provided separately to be connected to the trainer through jumper cables. The phase-shift RC circuit in the trainer kit used a single Op-Amp 741 while the Network model utilized an Inverting Amplifier to determine the gain which must be ≥ 29 times, therefore, Rfeedback ≥ 29 Rgain (Rfeedback = 30 kΩ and Rgain = 1 kΩ). Two tasks in this learning media were completed by students, namely measuring the output frequency and observing the phase shift. The output signal on this trainer kit was observed using only an Oscilloscope and a frequency counter. The phase inverter of the phase-shift RC Oscillator adjusts the output signal by 180o and sends feedback to the input, therefore, there is positive feedback. Meanwhile, the trainer kit had an output frequency specification of ~649 Hz (C = 100 nF, R = 1 kΩ) and it shifts the phase by 60o on each RC network. Using 2 and 3 R-C networks, the phase shifts were 120o and 180o, respectively. The trainer kit was packaged in a box made of acrylic with dimensions l x w x h = 20 cm x 28 cm x 5 mm. Through a questionnaire consisting of 13 criteria, this trainer kit was declared valid, namely r count > 0.2960 (5%) and reliable (Cronbach's alpha > 0.60, which was 0.732) to be used as a learning media based on user responses, namely students (N = 35). In the context of technical education, this trainer kit also supports the efficient implementation of practicum without compromising the learning objectives due to the ease of operation (plug & play through jumper cables) compared to fully assembling the circuit using a project board.
