  1. hi to all, i guess it wasn't that easy at all. building the amplifier circuit was not the main problem. we build it already and found out that the output sound was not that loud and clear. still there are some noise. the amplifier stage is the first out of three. we still need to connect it to ISD2560 to record and can playback the output sound. next to it is to display the counted heartrate sing LCD or 7segment. hope you have time answering my questions... thanks alot and Godbless...
