2. For the receiver chain shown below find the total effective noise figure (NF) at the input of the receiver. Assume the values G₁=-1dB, F₁=1.1, G₂=20dB, F₂=1.2, G3-6dB, F3-3, G4--3dB, F₂=2. Signal in G, F, IP3 1, 1 Filter G₂, F, IP3 2 LNA GF IP3 3 Mixer G,F 4 Filter 3. Referring again to the figure of problem 2, if the bandwidth of a channel is 100 kHz, find the additional gain needed (after the signal out shown) to amplify a signal that is just at the noise threshold at the input to the 13 dBm needed at the input of the ADC.
