This lesson covers the noise power calculation. It delves into the mathematical representation of noise voltage square using Planck’s black body radiation and explains the role of various constants in the equation. The lesson further discusses the concept of white noise and the conditions under which it is applicable. It also introduces the concept of noise power and how it can be maximized. The lesson then moves on to the concept of effective noise temperature and how it can be calculated for different devices. It also explains the concept of noise figure and how it can be calculated in terms of noise temperature. The lesson also focuses on how to measure effective noise temperature and the characterization of components. It concludes with the concept of noise figure and how to calculate noise figure in terms of noise temperature.

- Noise voltage square can be expressed using Planck’s black body radiation.
- Noise power can be maximized when the load resistance is the same as the resistance of the device.
- Effective noise temperature is a concept used to calculate the noise generated by different devices.
- Noise figure is a measure of signal to noise ratio degradation from input to output.
- Effective noise temperature can be measured using two inputs at different temperatures.
