WEEK 9: The Flowchart

Figure above shows the flowchart of the project

  • This is the flow of the project, it started from picking up sound from the heart through the chest piece.
  • Then the heart sound collected from the chest piece is transfer through the aux cable and the signal goes to the first part of amplifier circuit, which is pre-amplifier circuit.
  • The pre-amplified signal is then filtered by the filter circuit part, afterwards the filtered and amplified signal go through the power amplifier. 
  • At this part by having the LM 386 op-amp it will amplify and make it audible to be heard through the speaker.
  • Lastly, the output signal with Phonocardiograph display, heart sound wave, are display through the graphic LCD.

As conclusion, the flow of the project is plan as in the flowchart above. Nevertheless, the consequences, the project must be in this flow and in order to achieve the objectives.
