Abstract:
An apparatus for generating an electrical signal for use in biomedical applications, said signal based on at least four timing intervals T1-T4, said apparatus comprising:means for generating a set of at least four timing intervals T1-T4, said timing intervals having approximately the relationships (a) (2Ã—T2)&lE;T1&lE;(20Ã—T2), (b) 50 &mgr;sec&lE;(T1+T2)&lE;5000 &mgr;sec, (c) T3&gE;(10Ã—T1), and (d) 0&lE;T4&lE;500 msec; and means for combining said timing intervals into an electrical signal having an amplitude.
