Calculation example
Specifications: Central frequency, FO = 107 Hz
Q factor at maximum boost, Q+10 dB = 0.8
— Calculate QO, the sharpness of the simulated inductance itself.
QO = (R1 + R4)/R1 × Q+10dB
Note: R4 is from the separately issued internal block diagram.
≠ 4.270
— Calculate C1
C1 = 1/2
πF
OR1QO ≠ 0.536 (F)
— Calculate C2
C2 = QO/2πFOR2 ≠ 0.021 (F)
Sample results
Shelving characteristics (Band F5)
Achieving the desired control of 2-dB steps over the range between +10 dB to –10 dB requires choosing a
capacitor, C3, with an impedance of 650
.
