Sistem pengolahan sinyal dengan bahasa pemrograman turbo pascal

Abstract

Sebagian besar sinyal ditemukan adalah sinyal analog. Sinyal-sinyal analog ini tidak dapat diproses komputer karena dalam komputer proses yang berlangsung adalah proses secara digital. Supaya sinyal analog dapat diproses oleh komputer maka sinyal-sinyal tersebut hares diubah ke bentuk sinyal Pengubahan sinyal ini dilakukan oleh suatu interface yang dinamakan ADC (Analog to Digital Conventer). Setelah sinyal dikonversi ke bentuk digital, sinyal diproses oleh komputer. Proses di dalam komputer dilakukan oleh PPI (Programmabel Peripheral Interface) 8255, yang diubah ke sinyal digital. Supaya output yang dihasilkan oleh komputer berupa sinyal analog, maka sinyal digital basil pemrosesan PH 8255 dikonversi lagi ke bentuk analog oleh DAC (Digital to Analog Conventer). Sistem pengolahan sinyal yang dihasilkan dalam penulisan ini menggunakan bahasa pemrograman Turbo Pascal 7.0 serta bahasa Assembler untuk perancangan perangkat lunaknya. Most of signal were found analog signal. The analog signals can't be processed by computer because the process that occur iu computer is digitally process. So the analog signal must be changed into digital signal if the analog signal want to be processed. The signal nringt be changed by an interface which was named as ADC (Analog to Digital Conventer). After signal was converted to digital form, signal being processed by computer. This processing are worked by PH (Programmable Peripheral Interface) 8255. The product by PH process is digital signal. In order to get output ini analog signal, the digital signal which had been producted by PPI 8255 will be converted again become analog form by DAC (Digital to Analog Conventer). The Processing signal system have used Turbo Pascal 7.0 and Assembler for software design. . . This document is Unclip Institutional Repository Collection.
