I have a quick question. I know that a blocking cap. should block DC and pass AC. I even have a circuit to test that this is what should happen. But in SPICE I have no idea why I get this (pictured) behavior. Can someone please explain this to me?
I have a this square wave that goes from -2 to 0 volts as my input. The capacitor is pictured going into the input of a D/A, well a bunch of resistors to model it (not shown). Shouldn't the cap. raise the square wave up giving me a -1 to 1 volt square wave? Well I know it should, but my question is why does it not happen in SPICE?
Thank you.
