Abstract

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.

Abstract

The increasing demand for high-quality video delivery and storage has driven the development of more efficient video coding. H.265 is one of the latest video coding standards that provides better compression than its predecessor, H.264. This study analyzes the impact of intra and inter prediction configurations on video compression quality and efficiency in the context of H.265 encoding. The analysis is performed using Rate-Distortion (R-D) curves for several prediction configurations on each video sequence. The experiment compares intra, lowdelay, lowdelay-P, and randomaccess configurations on several video sequences. The results show that the intra configuration achieves the highest PSNR but also the highest bitrate. On the other hand, the randomaccess configuration achieves a good balance between bitrate and PSNR, obtaining a lower bitrate with better PSNR compared to lowdelay and lowdelay-P for all sequences.
