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 (µF)

Ž Determine C2

C2 =

≈ 0.014 (µF)

*: See the super bass block equivalent circuit diagram for the values of the internal resistors.
