Hi I am trying to merge a sinewave and a DC voltage so that the sinewave overrides on the DC voltage. The DC voltage is actually a pulse consisting of +24V and -12V pulses. The sincewave has a frequency of 500Khz and an amplitude of 10V pk. When I try to do it in LTspice, I cannot see any sinewave merged with the pulse train. I am attaching my circuit and when I try to see the waveform on the right end of the capacitor, I see only the pulse train and no sinewave. I tried to remove the capacitor and inductor and tried to see the waveform at the junction, but still I only see the pulse train. The sinewave is being generated, it is just that after the resistor, I cannot have anything about sinewave. Why is that happening in LTspice and how do I fix it?
