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 RSGADLink Copied

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.
