DOUBLE WAVEFOLDER
Cool – but a single wavefolding stage sounds a bit too tame for my taste.
So let’s fold
the folded signal again!
For that, we’ll simply add another wavefolding stage after the
first one’s output bu
ff
er.
Then, we’ll have to adjust the input attenuator’s range. That’s because we’ve previously
made sure that the input signal doesn’t cross the folding thresholds a second time. But in
order for the additional stage to have any e
ff
ect, it needs to. So we’ll simply replace the
100k input resistor with a 51k –
and the 4k7 baseline resistor with a 2k.
This roughly
doubles the attenuator’s range (while keeping the minimum volume the same),
allowing us to boost the signal to the necessary levels
.
Again, your kit is unfortunately missing extra 10k & 2k resistors, so we’ll also have to skip this
step on the breadboard right now. Feel free to set it up yourself if you have those values in your
stash.
You can try this chapter’s circuit in a simulator. I’ve already set it up for you right here:
you can change all values by double clicking on components.
