A typical connection of this amplifier is as follows:
Where the transfer function is given by
If R1 is fixed, one can obtain four time constants when the feedback resistor is replaced by the following schematic
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:
