Bi-pulse convertor (ON-topic)

[Mike Granger]

Seems like you could use two identical saw-to-pulse converters (comparators)
but feed them with pulse width control signals that  are inverted versions of
each other. This should increase pulse width of one while it decreases pulse
width of the other. You would need to have a diode connected to the output of
each comparator so that one would contribute the positive phase of the output
signal, and the other (diode connected opposite polarity to comparator output)
would contribute the negative phase. The other ends of the diodes would go to
the output jack.

Very interesting idea. Where did you hear of this?
