RUDHANTO, DONY S. (2009) PENGKONDISIAN SINYAL PADA RANCANG BANGUN SPEKTROSKOPI FTIR (FOURIER TRANSFORM INFRARED). Undergraduate thesis, Department of Physics, Diponegoro University.
The signal conditioned has been done at FTIR'S spectroscopy engineering so it can be read and processed in a computer. The signal condition is done in two ways, they are conditioned in hardware and software. In the hardware, the conditioned is done by conditioning analog signal that come from electromagnetic wave which is recived by IR Photovoltatic Detectors Thermoelectrically Colled censor by using amplifier circuit from Op-Amp. In the software, the signal conditioned is done using Delphi program by manipulating data received from ADC0804 become real data, that is data which are acceptable with value received by IR Photovoltatic Detectors Thermoelectrically Colled censor. As much as (42.5 ± 176,7) times from the censor emission power get strengthen signal conditioned that has been connected. Examining from the system totally is done by using gasoline sample. From the examining result, it is obtained data which is after being analized using Origin program can be found a chart showing gasoline compound spectrum.
