Greetings,
It sounds like there is a bug. The bilinear transform preserves stability,
but it can get into trouble with "delay-free loops" when there is feedback
around what is transformed.
Nowadays, I would digitize an analog circuit using Jatin Chowdhury's latest
code, e.g.,
Hi Dario,
The problem seems to be architecture-dependent. I am on a Mac (latest
non-beta software) using faust2caqt. What are you using?
I do not see the "strange behavior" you describe.
Your test looks good for me in faust2octave, with gain set to 0.01 (-40 dB,
which triggers the display bug
Hello,
recently I implemented and published a music plugin with faust [1],
which implements the digital model of a bass tone circuit.
A problem encountered during this process is the discretization of the
EQ section, located on the bottom part of the schematic [2], running
from C25 to C20 not
Hi, Julius.
I must be missing something, but I couldn't see the behaviour that you
described, that is, the gating behaviour happening only for the display and
not for the output.
If a remove the hbargraph altogether, I can still see the strange
behaviour. Just so we're all on the same page, the
