Time Domain Plots in Eddy (IFFT)

When creating time domain plots from frequency domain data, you must specify the parameters for the Inverse Fast Fourier Transform (IFFT):

  1. In the Report window, be sure the Domain is set to Time.
  2. In the Context section of the reporter dialog box, click IFFT Options.

The IFFT Options dialog appears.

  1. In the Input Signal section of the dialog select either Impulse or Step signal to use in performing the IFFT.
  2. For Step signal, input the rise time for the pulse. The rise time should chosen so that the frequency content is within the bandwidth of the available frequency sweep data.
  3. Select the Window Type from the drop-down menu.
  4. Enter the window Width in percent.

The Maximum Plot Time and the Delta Time are calculated based on the solution data available.
