With regard to stability under time varying modulation, Jean Laroche has
published some criteria:
Very interesting!
As to analysing the effect of parameter modulation on the output I guess
this is a job for state-space models?
Yes, I guess this is easiest to analyse in the state-space form.
allpass = 1 - 2*bandpass = (g^2-g*k*s-s^2)/(g^2+g*k*s+s^2)
Sorry
allpass = 1 - 2*bandpass = (g^2-g*k*s+s^2)/(g^2+g*k*s+s^2)
of course
