Graham, H

In the design of circuits where fast rising pulses of very high currents are desired, it has been difficult to determine the inductance of the capacitors and other circuit components involved. Due to the fact that, in order to make measurements, it has been necessary to add additional circuitry. This additional circuitry introduces serious errors that are difficult to evaluate. A method is described which is capable of determining the resonant frequency of L-C circuits involving inductances as low as .001 uH and net impedances as low as .001 ohm, provided the resonant frequency is below 15 mc. External circuitry does not effect the accuracy of measurement as this circuitry is not included in the parameters of the circuit being measured. It is possible to determine the effective resistance of the circuit being measured and thereby obtain the Q efficiency of the system.
