There is nothing in "time constant" that relates to frequency, transient

A Time Constant is also the -3dB point in a frequency response, hence
there is a frequency relation.

A Time Constant is proportional to square root of the rise time of a
transient, hence there is a transient relation.

It is not related. Ask any ham. That is my answer.

Find a ham that knows the answers (and it isn't Art).
