Preamp Gains: These responses reflect a preamplifier gain of 1. Gains can be adjusted by adding resistors to the A/D board to adjust for sensor impedance. If the gain has been adjusted in this manner, these responses will need to have their stage 2 gain adjusted accordingly.
Optional IIR DC Removal Filter: The responses given here that include the final IIR DC removal filter assume a low-frequency corner of 1 mHz (0.001 Hz). The corner can be set to any value of integer mHz between 1 and 1000 mHz. For other corner frequency values, the pole in stage 9 should instead be set to that corner frequency times 2 * pi.
