Abstract

Analog to Digital Converter (ADC) representing a component which can convert an analog signal to digital form signal. Ability like this required in digital data in a measurement or analyse analog signal. While interfacing represent an equipments consisted of hardware therewith the software made as link between “external world” with computer. One of technique interfacing which can be done is through parallel port.In this research, designed an interfacing use ADC 0809 through parallel port which can read wide till data 4 bits. So that in this scheme needed a multiplexer, what is used to chosen upper-bits or lower-bits which step into parallel port, so that the input which only own wide of data 4 bits can accept data from ADC owning wide of data 8 bits.The result, an equipments interfacing used to measure digital tension value from output ADC (analog to digital converter, using ADC 0809) to be presented at screen of computer, by real time.

Abstract

Penelitian ini bermaksud menelusuri judul tesis yang mirip, dengan batasan maksimal 256 karakter. Arsitektur yang digunakan adalah agent matcher dengan pembobotan dari kata-kata yang mirip, posisi dan urutan kata-kata yang dicari. Masing-masing pembobotan memiliki parameter yang berbeda-beda, dimana bobot ditentukan oleh peneliti berdasarkan pengalaman. Dua buah obyek dikatakan mempunyai tingkat kesamaan yang tinggi, yang ditandai dengan nilai distance yang mendekati nol.Hasil dari penelitian ini adalah daftar judul tesis yang mirip (dengan yang dicari) dengan tiga pembobotan yang sesuai dalam penetapan bobotnya. This study intended to explore more similar thesis title, with a maximum of 256 characters limit. Architecture used is weighting agent from the matcher with words like, position and order of the words searched. Each has a parameter weighting different, where the weight is determined by the researchers based on experience. Two objects said to have a high level of similarity, which is marked with a distance value close to zero. The results of this research thesis is a list of similar titles with three weighting in determining the appropriate weight.
