A typical connection of this amplifier is as follows:
Schematic diagram non-inverting amplifier
Where the transfer function is given by
Transfer function non-inverting amplifier


If R1 is fixed, one can obtain four time constants when the feedback resistor is replaced by the following schematic
Transfer function non-inverting amplifier
Time constants of equalisation:
Time constant associated with 500Hz: microsecond
Associated with 50Hz: microsecond
Associated with 2.122kHz: microsecond
Associated with 50kHz (used to prevent damage to the cutting head): microsecond
Resistor R1: Ohm




Results:
R2: Ohm
R3: Ohm
C2: nF
C3: nF
The transfer at 1kHz: (independent from R1) dB
