solarspatialtools.signalproc.interp_tf

solarspatialtools.signalproc.interp_tf(new_freq, input_tf)

Interpolate a transfer function in the frequency domain by magnitude and phase independently. This is necessary because the complex interpolation doesn’t really do the job on its own.

Parameters

new_freqnp.array or pd.Index

The new frequency index to interpolate onto.

input_tfpd.Series or pd.DataFrame

The transfer function to be interpolated

Returns

interp_tfpd.Series or pd.DataFrame

The transfer function interpolated to the new frequency axis. Type will match the type of the input.
