The tools of BLXX are DC, digital integrators/filters and your BLXX signals that
are bandlimited by definition, no sampling and no nonlinear operation involved.
So as there is no possible source for aliasing, there is no aliasing.
Okay. So in

I belive that, contrarily to the BLIT method, BLxx typically
integrates in the continuous time domain. I fail to see any reason why
should we prefer discrete-time domain integration.
i dunno. maybe to reprogram a capacitor requires desoldering it

Dear list,
Within EU Project ILHAIRE (www.ilhaire.eu) we work on detection, synthesis and
perception of laughter.
To this end, we'd like to invite you to participate in a brief (10 minutes)
online study that can be found here:
Hi,
Just a reminder that if you are new to the list you should read the
music-dsp FAQ. It contains answers to both technical _and_
adminstrative questions that often come up on the list. If your question
appears in the FAQ it is safe to assume that it has been discussed on the
list many times in
An interesting observation. Since
(t+a)^2=t^2+2at+a^2
the lowpass filtering of t^2 with a symmetrically windowed sinc gives
(sincw * (.+a)^2)(t)=
(sincw * (.^2+2a.+a^2)(t)=
(sincw * .^2)(t)+(sincw * 2a.)(t)+(sincw * a^2)(t)=
(sincw * .^2)(t)+0+a^2 =
(sincw * .^2)(t)+a^2
where * is
This means that in principle any piecewise polynomial signal
with bandlimited discontinuities of the signal and its derivatives
is also band limited.
Sorry if I'm missing something obvious, but what is a bandlimited
discontinuity?

Okay, but what does this consist of? If I've got some oscillator running at
time n, and I want to reset it its state around time n+1, what do I do?

Let’s back up a little…make that naive step at a high sample rate
(0,0,0,0,...,1,1,1,1…). Reduce the bandwidth in preparation to
downsample (with a steep low pass FIR set to cut off below half of
44.1 kHz), but don’t discard samples. Line it up (that is, account for
the delay in the FIR) with the
