Hello, list. I am experiencing some problems with NANs and I sometimes don't understand where they come from.
I have replaced all divisions with the condition that if the divisor is 0, the output is 0, otherwise it is x1/x2. I'm working with a self-oscillating FDN which uses tanh function for stability processing. There are also 6th-order fdelayltv units and the other processing in the system is mainly about 1-pole and 1-p-1-z filters that I have implemented in Faust. So there is arithmetic, some trigonometric functions and some other math like abs, min, max, sqrt and pow. I've tested the tanh function by putting it within a feedback loop with a huge feedback coefficient and it simply clips to 1. Are the fdalyltv likely to produce NANs is the signal setting the delay is not within the expected range? In your experience, what else is likely to produce NANs? Thanks, Dario
