Hello everybody , I'm intersted in building an ECG sensing module using some analog filters and digitize them , so is there anyone who could help.
THANKS

Thanks a lot Gorgon ,that's will be helpful as introduction.
I have done some search and came out with the following points:
-The ECG signal should pass through noise reduction( using notch filter) and some low pass filters.
-Then the clean(as I hope) analog signal will be an input to an ADC to output a digital data stream ( I found a 12 bit ADC)
At this point ,I want to interface that serial output through a wireless module to a PC to visualize the signal and analyze it.
I think there is a "serial to ethernet module" from IPSIL inc but i didn't find any useful information about it even on their site.
Is there an alternative low-cost wireless solution ?

Why 12 bit?, attempting to utilise that degree of resolution makes it MUCH more difficult, and the layout critical - as the lower bits are only likely to disappear in the noise. Using a cheap PIC with internal 10 bit A2D would be simpler, and probably still give more resolution than you really need.

hi Nigel Goodwin
what if i use a PIC and a BLUETOOTH MODULE to send the signal and let the laptop bluetooth detect using labVIEW ???
by the way i already test the module using hyper terminal with bluesoleil connected to CRYSTL and PIC16F877A and seven segment and its owrkign well with the ASCII ......
I am also doing a project on wireless transmission of ECG signals using bluetooth(or zigbee) with the help of ARM. Can someone help me with the ARM part??
