Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation. Fn = F1 + (F2 - 1 / G1) + (F3 - 1 / G1G2) + (F4 - 1 / G1G2G3) ....... and so on Where: Fn = The total noise of all stages together F1 = The noise factor of stage 1 F2 = The noise factor of stage 2 F3 = The noise factor of stage 3 G = Gain of respective stage Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation.
