I'm a newbie here. How can i send the output of the electronic stethoscope to computer through serial port ? I use MATLAB to receive the signal.
I need a ADC and a Microcontroller as well as the RS-323 to do that ?
The level of the signals must be shifted to the positive range before i can digitize it rite ?

Hi AudioGuru,
Thanks about the valuable informations. I was jz tring to calculate each op-amp's gain (necessary for my project report).
Currently learning to use ADC and ATMEL8051 for the interfacing purpose. Will post my results here for comments if there's a breakthrough.
I will use a standard electronic stethoscope which is sold on the market and compare the signals obtained from it with the electronic stethoscope 2 posted here. Try to calculate the percent root-mean difference between these 2 and analysis the quality of the circuit.
