1. A controller for an implantable device, the controller comprising a processor configured to:
control an electrical stimulus source to generate a first electrical stimulus to be applied to neural tissue, the first electrical stimulus defined by at least one stimulus parameter;
obtain a neural measurement from one or more sense electrodes, the neural measurement comprising an artefact; and
correlate the neural measurement against a filter template configured to detect a neural response evoked by the first electrical stimulus generated by the electrical stimulus source to determine a correlation;
determine a magnitude of the neural response evoked by the first electrical stimulus based on the correlation; and
use the magnitude of the neural response in a closed loop feedback circuit to determine the at least one stimulus parameter to control neuromodulation.
