Workbench.
1. järku inertne lüli
Sisend: nelinurkpinge 1 kHz
f0 = 0/2, 0 = 1/R*C, C = 1/ f0*R*2, R = 1/f0*C*2,
1. f0 = 1 kHz
2. f0 = 0,1 kHz
3. f0 = 10 kHz
1. C = 1,59*10-9 = 1,59 nF
2. C = 1,59*10-8 = 15,9 nF
3. C = 1,59*10-10 = 159 pF
1. R = 100 k
2. R = 100 k
3. R = 100 k
1. järku forsseeriv lüli
Sisend: nelinurkpinge 1 kHz
f0 = 0/2, 0 = 1/R*C, C = 1/ f0*R*2, R = 1/f0*C*2,
1. f0 = 1 kHz
2. f0 = 0,1 kHz
3. f0 = 10 kHz
1. C = 1,59*10-9 = 1,59 nF
2. C = 1,59*10-8 = 15,9 nF
3. C = 1,59*10-10 = 159 pF
1. R = 100 k
2. R = 100 k
3. R = 100 k
Integreeriv lüli
R1 = 9,1 k
R2 = 100 k
C = 3,3 nF
KdB = 20 log(100 k/9,1 k) = 20,8 dB
= 1/R*C = 1/100*103*3,3*10-9 = 3030,3 1/s
= /2 = 3030,3/2 = 482,3 Hz
