Before begin asking, here the datasheet for the IC https://www.analog.com/media/en/technical-documentation/data-sheets/AD8232.pdf
What I failed to understand is how the Instrumentation Amplifier amplify the ECG signal from electrode. It has an Integrator amplifier with C1 capacitor. As far as I know, integrator will integrate the input. If the input is EKG signal then fed to integrator, doesn't it change the output? I mean we expect the output of Instrumentation Amplifier is just input amplified but still in the same form. But with the presence of integrator amplifier to my understanding it will change the output form which no longer like EKG signal we saw in the input.
Please tell me where I am wrong. I would be happy if someone could explain from the input, GM1, GM2 and integrator working principle. Thank u
The output Vo still depends on integral of the Vekg
