Regarding integrator gain/frequency
An analog integrator SEEMS to have a transfer function T(s) = A/sRC where RC is a time constant and A is a SUPPOSED ”gain”, BUT it is a one-parameter term (A/RC)(1/s) – an unending/unbending downward 45 degree slope which can be thought of as varying up/down (gain) OR left/right (frequency):
It’s all one thing!
