It is simple to attenuate the signal to 5Vp-p with 2 resistors and bias it so that it is never a negative voltage.sugarmeaowl said:then how can i interface my circuti with the pc? using rs232?
how can i show the signalls on pc then?
Repeat: "It is simple to attenuate the signal to 5Vp-p with 2 resistors and bias it so that it is never a negative voltage."sugarmeaowl said:okk sirr i gott it that it will destroy the microphone port.
so what way do u recommend me to do it?
Of course the attenuator must be connected to the output of the ECG circuit. Check the max allowed input signal level of the mic input of your pc and make a suitable attenuator. Bias the signal so it never goes negative.sugarmeaowl said:what value resitors i can use? and shall i connect the resistors at the output of the ecg
