That is a good approach if you don't have the QUO. However, I believe the
QUO is probably quadrature phase triangle wave based with sine wave shapers
on the outputs. When I used the hold function, I noticed the sine wave
always resumes where it left off in the cycle, not where it would have been
had the wave been free running as in a filter oscillator type circuit.
