Abstract:
1. An apparatus for generating electromagnetic waveforms to stimulate a subject, comprising: a computing device generating digital waveform data; a digital-to-analog converter receiving said digital waveform data from said computing device and generating a corresponding analog waveform signal; a channel selector having output channels and operable to apply said analog waveform signal to said output channels when said output channels are actuated; a sequencer independent of said computing device, said sequencer comprising a timer for generating timing data, a selector circuit responsive to said timing data for selecting and actuating the output channels of said channel selector and a switch to condition said timer between different output pulse frequency modes; and an electromagnetic field generator coupled to each output channel of said channel selector, the electromagnetic field generator coupled to each actuated output channel converting said analog waveform signal into an electromagnetic waveform thereby to expose a subject wearing said electromagnetic field generators to said electromagnetic waveform.
