Filter ECG

Hi! I need to implement a bandpass filter for a cardiograph. I have little idea how to do it with this platform. The filter is from 0.05 Hz to 100 Hz. Any help I will be grateful. Greetings.

do you have already your pcb/hw designed? You can filter it in hw easily. I am aware of at least 2 filters (bandpass filter - low pass and high pass filter to allow only those freq) needed for ECG, but might needed more.

I would google fixed point low pass filter /high pass filter, there are many of implementation available on the internet. For example: http://ieee.ucsd.edu/wiki/tutorials/fixed_point_filtering_library

Search also here, tehre are couple of low pass/ high pass filter implementations. You might need to adjust coeff for your needs.
