Tone Circuit Constant Calculation Example
Bass Band Circuit
The equivalent circuit and the formula for calculating the external RC with a mean frequency of 100 Hz are shown
below.
Bass band equivalent circuit block diagram
1. We obtain C from mean frequency f0 = 100 Hz, as follows.
2. We obtain Q as follows.

Calculation example
Specification Mean frequency: f0 = 100 Hz
Gain during maximum boost: G = 12 dB
Let us use R1 = 0, R2 = 38.861 k
, R3 = 6.5 k
(assuming R1 = 0 during maximum boost) , and C1 = C2 = C.
