The completed digital stethoscope system was able to able to meet the various goals of the project. The system is able to perform the following key features: 1. Capture a cardiac signal using a custom-built acoustic sensor and an analog-to-digital converter 2. Output a real-time audio signal based on the sampled input using a digital-to-analog converter

Once in the digital domain, a microcontroller unit (MCU) or digital signal processor (DSP) performs signal processing, including ambient noise reduction and filtering, to limit the bandwidth to the range for cardiac or pulmonary listening. The processed digital signal is then converted back to analog by an audio digital-to-analog converter (DAC ...
