I am trying to understand why/when a purely ohmic voltage divider (impedences Z1 and Z2 are both resistors) would have a delayed response for high-speed, transient changes in an input voltage? Whether the input is high-freq AC, or simply a square wave with a sharp rise or sharp drop, I've been reading that a voltage divider with two resistors hits a limit in response speed and therefore resolution into the input signal, and yet there is no mention of frequency response in the idealized, basic equations -- e.g. V_out = (R2 / (R1 + R2)) * V_in.
Is there a way to quantify when a resistive divider would start losing resolution into a transient voltage source I am trying to measure?
