- ArbitraryPiecewise.getCharDecay(fieldType, times)[source]#
Compute characteristic decay function for arbitrary waveform.
This function describes the decay of the VRM response for the Linear problem type. Note that the current will be LogUniformized by its maximum value. The maximum current in the transmitter is specified in the source object.
- Parameters:
- fieldType{‘h’, ‘b’, ‘dhdt’, ‘dbdt’}
Field type.
- times
numpy.ndarray Observation times. These times MUST be during the off-time.
- Returns:
- eta(
n_times)numpy.ndarray Characteristic decay evaluated at all specified times.
- eta(
