Inserting a pulse to a LPF / HPF

How would the outputs look like in the following cases:

I know how the outputs would look like in the frequency domain, but I don't know how they'd look like in the time domain.

How do you derive it?

The LPF will have trouble following the rapid rise and fall of the leading and trailing edges of the pulse, but will tend to eventually follow the steady state high level and 0V values of the pulse.

The HPF will better follow the rapidly changing edges of the pulse but have relatively poor response to the steady state portions of the pulse.

Consider applying a pulse to a simple RC network configured either as a low pass network or as a high pass network.
