How to Calculate Overall Noise Figure of Cascaded Networks?
Overall Noise Figure of Cascaded Networks calculator uses Overall Noise Figure = Noise Figure Network 1+(Noise Figure Network 2-1)/Gain of Network 1 to calculate the Overall Noise Figure, Overall Noise Figure of Cascaded Networks is a measure of the noise performance of an electronic or RF (radio frequency) system, such as an amplifier, receiver, or any device that processes signals. It quantifies how much the device degrades the signal-to-noise ratio (SNR) of the input signal as it passes through the cascaded netwroks. Overall Noise Figure is denoted by F_{o} symbol.
How to calculate Overall Noise Figure of Cascaded Networks using this online calculator? To use this online calculator for Overall Noise Figure of Cascaded Networks, enter Noise Figure Network 1 (F_{1}), Noise Figure Network 2 (F_{2}) & Gain of Network 1 (G_{1}) and hit the calculate button. Here is how the Overall Noise Figure of Cascaded Networks calculation can be explained with given input values -> 1.169155 = 1.11+(1.21-1)/3.55.
