0 0 votes A negative resistance $R_{\text {neg }}$ is connected to a passive network $N$ having driving point impedance $Z_{1}$ (s) as shown below. For $Z_{2}(s)$ to be positive real, $\left|\text{R}_{\text {neg }}\right| \leq \operatorname{Re}_{1}(j \omega), \forall \omega$ $\left|\text{R}_{\text {neg }}\right| \leq\left|Z_{1}(j \omega)\right|, \forall \omega$ $\left|\text{R}_{\text {neg }}\right| \leq \operatorname{Im} Z_{1}(j \omega), \forall \omega$ $\left|\text{R}_{\text {neg }}\right| \leq \angle Z_{1}(j \omega), \forall \omega$ Control Systems gate2006-ec circuit-analysis network-solution-methods + – admin 546 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
