20.500.12556/RUL-84961 Digitalni osciloskop A digital oscilloscope Osciloskop je nepogrešljiva naprava v elektrotehniki. Z njo lahko opazujemo električni signal v realnem času in tako najdemo morebitne napake v delovanju električnega vezja. V diplomski nalogi je najprej predstavljeno delovanje analognega ter digitalnega osciloskopa. Predstavljena je osnovna terminologija, ki jo srečamo pri osciloskopih ter procesi, ki jih digitalni osciloskop izvaja. V drugem delu diplome izdelamo enostaven digitalni osciloskop, ki omogoča zajem signala, proženje ob različnih digitalnih dogodkih ter prikaz signala. V ta namen uporabimo razvojno ploščico STM32F4-Discovery, ki jo dobimo razmeroma poceni. Z njo zajamemo signal, ga preko vodila USB prenesemo na računalnik ter tam prikažemo. Da osciloskop testiramo, zajamemo signala PWM ter RS232. An oscilloscope is a fundamental device in electrical engineering. With an oscilloscope we can view the electrical signal in real time to help us find possible glitches in the electrical circuit. This dissertation starts off with a presentation of what an oscilloscope is. The basic terminology of oscilloscopes is introduced in this part along with an explanation of how an oscilloscope works. In the second part we create a simple digital oscilloscope, which can capture the signal and display it to the screen of a PC. For this purpose, we use a development board STM32F4-Discovery, which can be acquired at a reasonable price. We use it to detect a digital event on the signal and then capture it. Captured samples are transferred to a PC using USB protocol and are displayed to the screen. We test our digital oscilloscope by capturing PWM and RS232 signals. osciloskop signali vzorčenje proženje servomotor signal RS232 oscilloscope signals sampling triggering servomotor RS232 signal true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-09-08 16:10:04 2016-09-08 16:10:05 2022-08-02 06:42:55 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 19121 Obid_Matija_-_Digitalni_osciloskop.pdf Obid_Matija_-_Digitalni_osciloskop.pdf 1 4FD150E142C06AE24955423FB56E9A1D 6ff9556de26a6362cbeb633fc0b4f19bea767052ddefa1ae821b98de75e85bb2 f15692f9-a1b0-11eb-a523-00155dcfd717 20.500.12556/rul/60933839-16dc-4372-8445-57a329746869 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=88079 Fakulteta za računalništvo in informatiko 0 0 0
