Dear!  

I am using Altera DSP board DK-DSP-2C70N(Cyclone IIEP2C70F672C6) board. I want to interface ECG signal obtain from human body. Kindly tell me how to implement the same on this board.  

I have gone through the documentation of the board , there are many examples of generating the signal throgh DSP Ip cores and manipulating, but not on the external signal interface?????? 

 

Kindly help. 

Regards

The TI ADC input, as i see in reference manual, has a coupling transformer with high-pass spectrum and a low cutoff frequency of 1 MHz. ECG frequencies are very low, so they'll be strongly attenuated. So, the next option is using the audio CODEC with a good coupling analog circuit and instrumentation amplifier or adding an external ADC.
