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):
- In the Report window, be sure the Domain is set to Time.
- In the Context section of the reporter dialog box, click IFFT Options.
The IFFT Options dialog appears.
- In the Input Signal section of the dialog select either Impulse or Step signal to use in performing the IFFT.
- 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.
- Select the Window Type from the drop-down menu.
- Enter the window Width in percent.
The Maximum Plot Time and the Delta Time are calculated based on the solution data available.
