20.500.12556/RUL-155831 Sound-card-based Johnson noise thermometer This article presents a Johnson noise thermometer with a signal acquisition system based on a sound card. The thermometer uses a simple analogue circuit to measure the Johnson noise on a resistor. No external hardware or power supply is necessary, except for a reference multimeter. Data processing is performed in real time on a personal computer using LabView software. The results show that the developed thermometer has an expanded uncertainty (k = 2) of 0.8 °C over a temperature range from − 196 °C to 300 °C, with a measurement time of 5 min. measurements practical noise thermometer sound card meritve praktični šumni termometer zvočna kartica true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-22 11:39:55 2024-04-22 11:39:58 2024-05-14 08:46:00 0000-00-00 00:00:00 2024 0 0 6 str.
