Hi Ross,
since you opened this topic, I thought I'd try to share the intermediate
results my findings, as much as I can remember them (that was a few
years back). Most of them concern the continuous time case.
First note regarding the continuous time case is that cutoff modulations
do not

That's why I was somewhat surprised that you simply managed to
restrict the eigenvalues of the system matrix in some coordinates.
To be clear: the eigenvalues of the transition matrix only cover
time-invariant stability.
The constraint for time-varying
With reference to my previous message:
It looks like there is a change of basis matrix T that can be used to
satisfy Laroche's Criterion 2 (time varying BIBO stability at full audio
rate), at least for k 0.
T:
[ 0, 1]
[ 1, -1/1 ]
This matrix requires k 1/1 but it seems
