ABSTRACT
This article describes how to develop a practical new type of digital heart sound signal detection device that can achieve quantitative and accurate capture of human heart sounds and records. According to the mechanism and characteristics of the heart sound signal, the goal of this system design is to set the platform. The system uses a contact-type piezoelectric film microphone, which can effectively pick up the effective frequency band of the heart sound, then amplify and filter the collected original signal, and perform preliminary verification on the system to obtain the desired heart sound signal.
