Question

Enlist the properties of noise. What is thermal noise, shot noise, burst noise. What is noise

Answer 1

Thermal noise is caused by the thermal agitation of charge carriers (electrons or holes) in a conductor. This noise is present in all passive resistive elements. Like shot noise, thermal noise is spectrally flat or has a uniform power density, but thermal noise is independent of current flow.
