0.5 mV–100 mV. When measured on maternal abdomen fECG is additionally dis-
turbed by the muscular activity from abdomen and uterus, since the main frequency
range of fetal and maternal ECG is in the frequency range 0.3–100Hz, while for the
abdominal muscle it is 10–400 Hz and for uterine contractions 0.01–0.6 Hz. There-
fore the problem of extraction of fECG from other disturbing bioelectric signals is
not a simple one. An example of mECG extraction from abdominal ECG is shown
in Figure 4.39.
