help with circuit problems
i'm now doin research on ECG circuit. i dun really understand one of the ECG part,amplifier+filter part. the part containing Differential amplifier+2nd order BPF+inverting amplifier+summing amplifier.
can someone tell me why...
-we need inverting amplifer?why cant we jus amplify the signal during differential ampifier then pass to BPF filter out the noise then ok de
-why we use 2nd order BPF instend of 1st order?wat is the different
thx for answering my topic !!!!!
