Loudness Function External Circuit Constant Calculation Example
First, refer to the LC75366 and LC75366M 10 dB step internal equivalent circuit shown on page 5. Figure 1 below
shows this circuit simplified with the external components used for the loudness function connected for this calculation.
The sample calculation below uses this diagram to acquire a 5 dB boost at f = 100 Hz.
(f = 100 Hz, 5 dB boost)
Let R and C in Figure 1 be:
R1 = R2 = 10 k
R3 = 1 k
C1 = Z1, C2 = Z2
Then:
Solving the above equations gives:
Z1
≠
178.3 k
and Z2 = 176
