Noise fundamental experiment is one of the most important tools to study noise in any electronic system and instrument. The noise present in all electronic signals limits the sensitivity of many measurements. The thermal noise generated by a resistor at room temperature or the shot noise in diode and transistor can be studied by using this experiment. You can see noise on the display of an oscilloscope and also play with it by changing parameter of noise like temperature and bandwidth.
