# ImpedanceRatio

Tool for plotting voltage attenuation or impedance at a specific measurement and injection site as a function of log frequency from 0.1 to 1000 Hz.

The measurement site is selected by first selecting the SelectMeasure item of the SelectLocation menu and then selecting a location on the neuron in the middle panel. A red dot denotes the measurement location. The injection site is selected by via selection of the SelectInject menu item. Measurement and injection sites are indicated by red and blue dots respectively. The SwapMeasure/Inject menu item swaps the measurement and injection sites.

The Plot menu specifies whether to plot log attenuation (default), input impedance, transfer impedance, or `V(measure)/V(inject)`. Input impedance is plotted with respect to the measurement site and the injection site is unused.

This tool uses the `Impedance` class to calculate voltage attenuations.
