161 Noise Fundamental Experiment The Noise Fundamental Experiment is one of the most important tools to study the 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 setup. The noise can be observed on the display of an oscilloscope and alsomanipulate it by changing parameter of noise like temperature, bandwidth and other parameters.
