9.6. Problems
1. An ideal resistor of 1 kΩ is coupled in parallel with an ideal capacitor with capacitance 2.2 μF. Calculate the complex impedance and the complex admittance at 314 Hz.
2. Suppose that we have obtained the measurement results shown in Table 9.6. The table contains raw data, as for instance obtained directly from a lock-in amplifier. It is admittance data according to Y = G + jB, and the results are given in microsiemens.
a. Calculate the corresponding impedance values at each frequency.
b. Plot complex admittance as a function of logarithmic frequency, with linear and logarithmic conductance/susceptance scales. Is there a second dispersion below 0.1 Hz?
c. Plot the admittance and impedance data in a Wessel diagram and compare. From ...
