hello i am trying to find the the capacitance voltage of a circuit that has a steprespost 30 u(-t) where at t<0 u(-t)= 1 and where the t>0 u(-t) = 1-u(t)
caN SOMEBODY HELP ME ON HOW TO DEAL WITH THIS STEP RESPONSE SUBSTITIONS

THANKS

You have to provide on details on how the RC circuit looks like. Is it voltage driven, current driven? Is the voltage taken across the resistor or the capacitor? Your question (as you have stated) is not clear. You must be a bit more clear if you want responses to your question.
