A particular communications system has 2 identical receiver stages connected in cascade, each with gain 7 dB and noise figure 4 dB. Compute the noise figure of the combination assuming the stages are impedance matched. Repeat for 3 identical stages with the same properties. What about the hypothetical case of a large number of stages? What does that imply in terms of the properties of the first stage?
