131) Re u0∗ H(s0 )u0 − |s0 | 0 For ω0 = 0, Eq. 130) becomes Re [u0∗ H(σ0 )u0 + u0 H(σ0 )u0 ]. Writing u0 = 0. 131) (see Prob. 14). In the situation where σ = 0, a similar inequality can be derived. 129) we replace e2σ0 t /σ0 by t. 131) is valid for all s0 0, ω0 = 0. The details are left as an exercise (see Prob. 15). 131) for ω0 = 0 and Re u0∗ H(s0 )u0 0 for ω0 = 0. 127) with u0 complex corresponds to an excitation uˆ exp(σ0 t) with uˆ 0 real, where uˆ 0 = Re u0 . 128) is the response, we implicitly assume that we have already set up appropriate initial conditions inside the n-port network such that when the excitation u(t) is applied at the time t = t0 , no transient occurs at t0 and thereafter, and the voltages and currents appearing at the ports behave exactly as specified.

PROOF. From Eq. 157) we see that the theorem is clearly true for all the points on the real-frequency axis. Thus, we consider the situation where s0 = σ0 > 0. 158) holds, Hh (σ0 ) must be nonnegative definite. 158) follows. 8. This completes the proof of the theorem. A problem of great practical interest is to determine the maximum frequency of sinusoidal oscillation. For this we define the following. 10: Maximum frequency of oscillation The largest ω on the real-frequency axis at which an n-port network is active is called the maximum frequency of oscillation of the n-port network.

22 is the small signal T-equivalent network of a transistor. 171) which is nonnegative definite if and only if det Zh ( j ω) = re rb − α2 4ω2 C2 † Strictly speaking, the fastest regenerative mode is σ − , m → 0.
