Through the tube...
Hello all,
something completely different...
there was some recent discussion on the forum about modeling guitar amplifiers.I have been wondering for quite a while, whether the methods that I use to model radio frequency power amplifiers might also work for audio applications.
It's been a rainy day, so I found the time and energy for some experiments. Just for fun.
The device-under-test is a preamplifier with a single 12AX7 tube:
My good ol' Kurzweil (not in the picture) serves as "signal...
Instant CIC
Summary:
A floating point model for a CIC decimator, including the frequency response.
Description:
A CIC filter relies on a peculiarity of its fixed-point implementation: Normal operation involves repeated internal overflows that have no effect to the output signal, as they cancel in the following stage.
One way to put it intuitively is that only the speed (and rate of change) of every little "wheel" in the clockworks carries information, but its absolute position is...
