Abstract: | A simulation signal source of heart sound signal is constructed by TINA-TI voltage generator and a microphone sensor model is constructed by using voltage control current source. On this basis, the heart sound signal amplification and filtering circuit is designed, and the circuit simulation and analysis are carried out to guide the actual circuit design. Practice shows that the experiment can effectively guide the design and manufacture of practical circuits through virtual simulation analysis, and achieve good experimental teaching results. |
