plotted a smooth rising curve for V(output) but after adding the apparently unconnected Schmitt oscillator the plot of V(output) appears to be chopped at 50Hz, the frequency of its AC source. How can I plot both V(output) and the oscillator V(out) correctly?
Just realised I had the ground attached to the AC source, mea culpa
