1. A system for detecting bioelectrical signals, the system comprising:
a reference module having a reference electrode to detect a reference electrical signal;
an electromagnetic field (EMF) detection module having:
an antenna configured to detect an EMF signal;
an antenna circuit configured to amplify the EMF signal; and
a single-ended amplifier configured to produce a bioelectrical signal based on the amplified EMF signal;
a receiver module having:
an impedance matching circuit configured to match a source impedance of a prior stage; and
a signal processing module having a processor configured to (1) perform a time-domain analysis, and/or (2) perform a discrete wavelet transform (DWT).
