.. py:class:: nibcq.enums.InterpolationMode

   Bases: :py:obj:`str`, :py:obj:`enum.Enum`


   Interpolation modes for compensation value lookups in frequency domain.

   Defines how compensation values are calculated when the measurement frequency
   doesn't exactly match a frequency in the compensation table. Different modes
   provide different trade-offs between accuracy and computational simplicity.

   Values:
       NEAREST ("nearest"): Nearest neighbor interpolation
           - Uses the compensation value from the closest frequency point
           - Fast and simple, but may introduce step discontinuities
       LOWER ("lower"): Lower bound interpolation
           - Always uses compensation value from the next lower frequency
           - Conservative approach, ensures no extrapolation above known points
       UPPER ("upper"): Upper bound interpolation
           - Always uses compensation value from the next higher frequency
           - Conservative approach, ensures no extrapolation below known points
       LINEAR ("linear"): Linear interpolation
           - Calculates compensation value using linear interpolation between
             neighboring frequency points
           - Most accurate for smooth frequency responses

   .. rubric:: Examples

   >>> compensation = Compensation.from_file(CompensationMethod.SHORT, "short.json")
   >>> impedance = compensation.get_compensated_impedance(
   ...     frequency=1500.0,
   ...     measured_impedance=complex(0.1, 0.05),
   ...     interpolation_mode=InterpolationMode.LINEAR
