Hi guys
i built an ECG system(preamplifier and filters), but i faced a problem in the filters:
the standard of ECG filters is 0.1 Hz cuttoff frequency for highpass filter and 100 Hz for lowpass filter
but i only obtain a good ECG signal when i make the cuttoff frequency of highpass filter 1 Hz and lowpass of cutoff frequency 80 Hz(8 order)
is my ECG filters correct(1 Hz and 80 Hz)?
or the filters cuttoff frequencies should be as the ECG filters standard?
i ask this question because i am writing a research paper.
