phonocardiogram

Post by spark » Sun Jul 23, 2006 5:47 am

m designing a phonocardiogram-auscultation device for my project using an electret condensor microphone followed by a band pass filter amplifier circuit of gain 1000 (20 to 2000 Hz). any suggestions/ ideas please.....

will it work with a buzzer plate instead of mic? how dependable is a mic?
