2. Treble Band Circuit
The treble band circuit can provide shelving characteristics. Here we present the equivalent circuit when the circuit is
providing boost and the circuit calculation formulas.
Treble band equivalent circuit
Sample calculation
Specifications: Set frequency, f = 26,000 Hz
Gain at maximum boost: G+12 dB = 12 dB
Assume R1 = 12,840
and R2 = 38,834 .
Substituting the above values into the following formulas allows us to solve for C.
