ABSTRACT:
An apparatus for measuring an electrogastrogram and an intestinal electrogram including at least an electrode fixed to a body surface, an amplifier for amplifying a potential detected by said electrode, a low-pass filter for removing frequency signals other than the potentials of the stomach and the bowel amplified by said amplifier and a recorder.
The relationship between the frequency of the input signal of said low-pass filter and the phase of the output signal is made linear.
