Question

For the circuit of Figure 1:

(a) If R = 560 Ω, L = 1 H, and C = 0.5 μF locate the poles and zeroes of Z_EQ(s)?

(b) If we were to increase the resistance to 10 kΩ, how would the poles and zeroes change?

Question:

Find Z_EQ1(s) and Z_EQ2(s) for the bridge-T circuit in Figure 2. Express each impedance as a rational function and locate its poles and zeroes.
