dc.description.abstractIn the market, there are many types of pulse oximeters and electronic stethoscopes which can be easily purchased off the shelf. These equipment on their own allow users to draw sufficient information according to their respective functions. But to base on the information gathered individually, it does not suffice users to analyse respiratory signals abnormalities of the subjects under test. This project describes the acquisition and analysis of respiratory signals collected via simple means. In addition to that, it also illustrates the Pulse Plethysmograph amplifier and Electronic Stethoscope circuits which are used in aid to collect various respiratory signals. This project uses the Pulse Plethysmograph amplifier circuit to capture the beating of the heart to be recorded without the need to make direct electrical connections to the body. While the Electronic Stethoscope is used to capture the internal sounds of the body, (ie chest area). Following that, the signals captured from the circuits via the NI USB-6215 are digitized and output as waveforms in the LabVIEW SignalExpress software, which will then be saved as .txt files. With that, MatLab was used to process the .txt files and analysis to be carried to compare and observe respiratory abnormalities of the subjects under test.en_US
