Hi Folks,
I am working on a medical instrument, like an ECG, and searching trough the net, there are some unclear point about the instrumental amplifier usage:
I am working on a medical instrument, like an ECG, and searching trough the net, there are some unclear point about the instrumental amplifier usage:
- As you can see in the image, there is a far less resistor to set the gain, and parallel to it, two more in series with each other. What is good for this circuit instead of the 2 series resistor:
