Treble Band Circuit
The treble band circuit can provide shelving characteristics.
This section presents the equivalent circuit for boost operation and the calculation formulas.
Sample calculation
Specifications: Set frequency: f = 26,000 Hz
Gain at maximum boost: G+10 dB = 10 dB
Assume R1 = 16.240 K
, and R2 = 35.461 K.
The constants mentioned above are calculated as follows.
