Individual Wave Component Signal Modeling, Parameters Extraction, and Analysis

Universal Journal of Gastroenterology and Hepatology | Vol 1, Issue 1

Figure 11

Spectrograms of recorded bowel sounds from a patient with an empty stomach. The top figure is the original recorded bowel signal. It shows a lot of activities once the bowel movement starts. The bottom figure shows the reconstruction of a series of indi vidual wave components. The echo signals from the main individual wave components bounce against the digestive system’s empty wall, creating more individual wave components but at a lower intensity.
