Abstract
Methods, systems, and apparatus for signal detection are described. In one example, a detection assembly includes a signal detector. The signal detector is configured to receive a sensor signal having a peak magnitude and a first frequency and generate an output signal having a magnitude proportional to the peak magnitude of the sensor signal and having a second frequency less than the first frequency of the sensor signal.

A neural signal detector comprising:
- a rectifier circuit configured to receive a time varying neural signal having a first frequency from a neural sensor and output a rectified signal corresponding to the received signal;
- and
- a peak detector circuit operatively connected to the rectifier circuit to receive the rectified signal and configured to provide an output signal comprising a positive square wave having a peak magnitude proportional to a peak magnitude of the rectified signal and having a second frequency less than the first frequency of the neural signal.
