10.3.4 Skip frequencies
Description
With certain output frequencies, mechanical resonances might occur (e. g. fan).The skip
frequencies suppress these unwanted output frequencies. The bandwidth (
nf)
determines the skip frequency range.
The function is in the block NSET1 before the ramp function generator.
