In Figure 1733 the network Na is an active device with h-parameters h11 20 kV, h12

In Figure 17–33 the network Na is an active device with h-parameters h11 ¼ 20 kV, h12 ¼ 0, h21 ¼ 5  103, and h22 ¼ 50 mS. The network Nb is a resistive feedback circuit with z-parameters z11 ¼ 2R and z12 ¼ z21 ¼ z22 ¼ R. Find a value of R such that the voltage gain of the series connection is TV ¼ 2.
