Temperatuurääriuus
Temperatuurääriuus, often translated as temperature noise or thermal noise, is a fundamental phenomenon in electronic circuits. It arises from the random thermal motion of charge carriers, typically electrons, within a conductor. This random movement causes fluctuations in the charge distribution, leading to a small, fluctuating voltage across the conductor. The magnitude of this voltage is directly proportional to the temperature of the conductor and the bandwidth of the measurement.
This noise is present in all electronic components that have a non-zero temperature and contain charge carriers,
Temperatuurääriuus is a significant factor limiting the sensitivity of electronic measuring instruments and communication systems. In
