Abstract

The quality of an audio system is greatly influenced by the accuracy of frequency distribution, especially in the low-frequency range managed by the subwoofer. To achieve optimal separation, this study presents the design and implementation of a fourth-order active analog Linkwitz"“Riley crossover filter (LR24) for subwoofer applications. The LR24 topology was selected for its ability to provide smooth and symmetrical frequency transitions with a 24 dB/octave slope. The research covers filter and preamplifier design, component selection, and performance evaluation using pink noise. Measurements were carried out through spectrogram analysis, frequency spectrum observation, and oscilloscope testing. The resulting filter achieved a cutoff frequency of 126.8 Hz with an attenuation slope of 24 dB/octave at 249.4 Hz, effectively reducing high-frequency signals. Comparative analysis with fourth-order digital Butterworth and Bessel filters on the DBx 260 demonstrated that the proposed analog design delivers competitive performance. This work highlights that an analog LR24 filter built from basic components and general-purpose op-amps can serve as a reliable and cost-effective alternative to digital solutions in low-frequency audio processing, although its performance is still constrained by the limitations of standard op-amps compared to audio-grade devices.

Abstract

The Yagi antenna is a type of directional antenna designed to enhance signal reception and transmission in a specific direction. In this study, the MMANA-GAL software was utilized to design and simulate the antenna with a high level of accuracy. The aim of this research is to design and implement an 11-element Yagi antenna capable of capturing signals from a Base Transceiver Station (BTS) to improve weak signal quality in Menyabo Village. Antenna testing was conducted using the MMANA-GAL application for simulation, along with SpeedTest and GNetTrack (GNet-WiFi) applications for measuring signal performance. Based on the results of the design, simulation, and testing phases, it can be concluded that the designed antenna meets the desired specifications. Simulation results indicate that the 11-element Yagi antenna has an impedance of 50 Ohms, a VSWR value of 1:1.00, and a gain of 12.8 dBi. Field testing results demonstrated improved signal performance. Prior to connecting the antenna, SpeedTest results showed a ping of 61 ms, download speed of 0.40 Mbps, and upload speed of 1.70 Mbps. After connecting the antenna at a height of 10 meters, the values improved to a ping of 39 ms, download speed of 1.06 Mbps, and upload speed of 1.46 Mbps. At 12 meters, the results further improved to a ping of 38 ms, download speed of 2.67 Mbps, and upload speed of 1.58 Mbps. Regarding RSSI measurements, before connection, the signal strength was -77 dBm. After connecting the antenna, the RSSI improved to -51 dBm at 10 meters and -41 dBm at 12 meters. Based on these findings, it can be concluded that the designed 11-element Yagi antenna successfully enhances signal quality and meets the targeted specifications.

Abstract

Digital television is a device used to capture digital TV broadcasts, this type of television uses digital modulation and compression systems to broadcast image, sound, and data signals to television sets. The need for this technology requires a device that can work to carry out the digital TV communication function. One very important communication device is the antenna. B iquad antenna is a loop antenna with a rectangular contour and is paralleled to get a smaller impedance. Wireless communication is inseparable from the existence of antenna devices. This research only focuses on analyzing signal reception on digital TV frequencies 478-694 MHz and on antenna design. This research discusses the design of a digital TV antenna with an RF amplifier and analyzes the parameters of the antenna design results and optimizes the antenna design to fit specifications. Simulation results on CST studio show that the biquad antenna has a VSWR value of 1.64, return loss of -12.26 dB, bandwidth of 114.44 MHz, gain of 9.080 dBi, and directivity of 9.253 dBi. These parameter values are obtained after performing an optimization process from previous simulations that still do not meet specifications. In the correlation of digital TV, antennas with RF amplifiers are able to capture very good signal strength and quality on each channel on the digital TV screen so that good image quality is obtained.

Abstract

In the rapidly evolving digital era, the demand for super-fast internet continues to increase. FTTH (Fiber To The Home) is a solution with fiber optics that provides a direct connection to the customer's home, offering high bandwidth and stable internet speeds. This study simulates an FTTH access network using Optisystem software to evaluate network feasibility through parameters such as power link budget, rise time budget, BER, and Q-Factor. The simulation results show excellent network performance, with minimal difference between the calculation and simulation results, especially at the downstream side receiver attenuation value (Prx). All grades still meet the set eligibility standards. Testing of the rise time budget with NRZ coding shows results below the specified limits. The analysis of the eye diagram on the BER Analyzer shows excellent acceptability quality with a wide eye-height opening. The performance of the FTTH network is rated as excellent based on the results of calculations, simulations, and direct measurements in the field, although there are slight differences caused by factors such as safety margin values and attenuation of network components. In conclusion, simulations using OptiSystem are effective in measuring and ensuring the feasibility of FTTH access networks.
