I am given an ideal OP-AMP like this (R-resistor, Cap-capacitor): Code (Text): ____+Cap-_ | | ___R____|__|\______|_____ + | -|/ + | V in | V out - | | | |_________|______________ - and V in is given as a step function like so: Code (Text): /\ (volts) | |____1____2_______> (t, sec) |____| (-2) | | that is V(in) is -2 on [0,1] and then 0 further. I need to find V(out) at 2sec. So far I think I got the expression I need to work with. V(out) = -Vc Vc = 1/(RC) * integral(V in dt) But my problem is how I deal with a step function in this case of integration. Any help is appreciated. Thanks.
