DESAIGN AND SIMULATION OF ADC CIRCUITS COMPILED BY IC ADC0804 AND IC ADC0809

Amril, Muhammad, Sihombing, Panangian Mahadi, Sukarwoto, Sukarwoto
Abstract: Abstract: Medan Aviation Polytechnic is one of the campuses under the ministry of transportation which has a major in telecommunication and air navigation engineering in Indonesia. Based on field surveys, an Analog to Digital… gital Converter (ADC) practicum kit is needed to improve the ability of cadets. Based on this background, this study aims to design and simulate two ADC circuits, each of which is compiled by the integrated circuit (IC) ADC0804 and IC ADC0809 respectively. Three statistical formulas, namely mean error (ME), standard deviation error (SDE), and root mean square error (RMSE) are used to measure the performance of the two ADC circuits. Both ADC circuits are simulated using a Proteus 8.11 Simulator with 255 analog input voltages. Based on the result of the study, it is known that the ADC circuit compiled by IC ADC0809 is more accurate than the ADC circuit compiled by IC ADC0804. This is evidenced by a smaller error value, which is based on the simulation results of the ME, SDE, and RMSE values were 0.4210, 0.3410, and 0.5110, respectively. And, based on the measurement results, it has ME, SDE, RMSE respectively, namely 0.8510, 0.8110, and 0.9310.             Keywords: ADC; Proteus 8.11 Simulator; IC ADC0804; IC ADC0809; ME; SDE; RMSE     Abstrak: Politeknik Penerbangan Medan adalah salah satu kampus di bawah Kementerian Perhubungan yang memiliki jurusan teknik telekomunikasi dan navigasi udara di Indonesia. Berdasarkan survei di lapangan, kit praktikum konverter analog ke digital diperlukan untuk meningkatkan kemampuat taruna. Berdasarkan latar belakang tersebut, penelitian ini bertujuan merancang dan mensimulasi dua rangkaian ADC yang masing-masing disusun oleh IC ADC0804 dan IC ADC0809. Tiga formula statistik, yaitu mean error (ME), standard deviation error (SDE), and root mean square error (RMSE) digunakan untuk mengukur kinerja kedua rangkaian ADC tersebut. Kedua rangkaian ADC tersebut disimulasi menggunakan Simulator Proteus 8.11 dengan 255 tegangan masukan analog. Berdasarkan hasil penelitian diketahui bahwa rangkaian ADC yang disusun oleh IC ADC0809 lebih akurat dibandingkan dengan rangkaian ADC yang disusun oleh IC ADC0804. Hal tersebut dibuktikan dengan nilai kesalahan yang lebih kecil, yaitu berdasarkan hasil simulasi memiliki ME, SDE, RMSE masing-masing adalah 0,4210, 0,3410 dan 0,5110. Dan berdasarkan hasil pengukuran memiliki ME, SDE, dan RMSE masing-masing adalah 0,8510, 0,8110, dan 0,9310.   Kata kunci: ADC; Simulator Proteus 8.11; IC ADC0804; IC ADC0809; ME; SDE; RMSE

Using the eXtended Finite Element Method (XFEM) to Simulate Own Frequency under External Influences of a Closed System based on Dynamic Compensation Method

Nguyen, Huu-Dien
Abstract: Many mechanical systems with elastic and damping properties are prone to resonant phenomena at natural frequencies under the action of external forces. Resonance phenomena can also be preserved in control systems of such… objects closed by negative feedback, which reduces the quality of the functioning of these systems. The paper under review deals with the practically important problem of suppressing oscillations at natural frequencies in control systems for a linear oscillator, which is traditionally considered a dynamic object described by a second-order differential equation with complex roots of the characteristic equation. The focus of the work is the question of the roughness of the system in relation to inaccurate knowledge of the resonant frequency of the controlled object (which is typical for many technical applications).
