outputs the order, V in .TRAN and dB/deg in .AC , active at all times; |

in .TRAN , if test=1 and sim=<simulation time> , the time span is divided in 4 and the pin outputs the values of the lower pass-band, lower stop-band, upper pass-band and upper stop-band frequencies, in this order, as calculated internally; |
0.3 |
in .TRAN , if test=1 and sim=<simulation time> , the time span is divided into 6 for each term of the bilinear transform: A2, A1, A0, B2, B1 and B0 , in this order; then, each part is again divided into N parts and the pin outputs the values of each term from [1:N] ; for LP and HP, each 1/6 th segment will be split in two and only the first half will have valid values; BP and BS use all the segment.
Note: The coefficients are not normalized, i.e the denominator's are not divided to B0 , or similarly for the numerator. |

I/O pin for sampling clock, needs SH=1 . For external sync set f0 negative. It has two I/O resistances:
f0>0 |
R=1Ω |
f0<0 |
R=1GΩ |
This way, if more than one filters are in the schematic and their clocks are the same then one of them can have the master clock (f0>0 ) and the others can be driven by it (f0<0 ). |
