Using the indicated parameters for each system element (P in,
G1, L & G2) and with impedances matched for each junction
(node, Ni ) of this end-to-end system, compute a) the net linear
system gain, b) the net system gain in dB, and c )the power levels
(in dB) at each stage of this cascaded system (i.e. Pin, N1, N2,
and P out). Pin=0.1 W, G1=400, L=2,000, G2=500
