• Figure 1. Extra logic added to the original circuit now gives half a cosine on each trigger pulse, with alternating polarities, generating a square wave with smoothed edges
• Figure 2. Some waveforms from the circuit in Figure 1
• Figure 3. The target step-function is a logistic curve; a segment of a cosine is shown for comparison
• Figure 4. Adding the components in red gives a much better fit to our target curve. The tri-wave amplitude is increased and can now be squashed even more
• Figure 5. Waveforms after adding the mods shown in Figure 4
• Figure 6. Comparison of the target curve with part of the trace D in Figure 5
