Analyzing Time-Domain Signatures
The time-domain response of a device, its signature, provides specific circuit detail. The shape
of the response indicates the element type and configuration (series or shunt). Its value and
location can be determined from the size of the reflection and its time delay. In general, a
wider measurement bandwidth will provide finer response resolution. The following table,
