Abstract :
The recording of gastric activities by surface electrodes is called electrogastrography (EGG). It should be carefully filtered and amplified because of its ultra-low frequency, tiny and noisy signal. A new system, including a signal acquisition device and Windows-based software, was designed to record and analyze the EGG signal. Many volunteers and patients have been successfully tested by the system
