Super Bass Block Circuit 1 External Capacitor Calculation Example
The LC75373E external capacitors function as the structural elements for simulated inductances. This section presents
the equivalent circuits and the formulas used to calculate the desired center frequencies.
Simulated Inductance Equivalent Circuit
Sample Calculations
Specifications:
Center frequency: F0 = 100 Hz
Q at maximum boost: Qmax = 1.05
x Determine the sharpness Q0 of the simulated inductance itself.
Q0 =
* Qmax
≈ 2.6481
Determine C1.
C1 =
≈ 0.60 (F)
Determine C2
C2 =
≈ 0.014 (F)
*: See the super bass block equivalent circuit diagram for the values of the internal resistors.
