so I have a LC low pass filter and I give it a step input like so in LTSpice
Now the inductor and capacitor are ideal with very high Q and no parasitic R. So the resulting Vout is a sine wave oscillating at the resonant frequency. My question is why does the amplitude of the sine wave go as high as 2V for a 1V step input?
I want to understand, intuitively, why the voltage on the cap increases to 2V at its peak.
