Deemphasis (DEEM, FSI1, FSI2 pins or FDEEM, FFSI1, FFSI2 flags)
The digital deemphasis filter is an IIR filter with var-
iable coefficients to faithfully reproduce the gain and
phase characteristics of standard analog deemphasis
filters.
The filter coefficients are selected by FSI1 (or FFSI1
flag) and FSI2 (or FFSI2 flag) to correspond to the
sampling frequencies fs = 44.1, 48.0 and 32.0 kHz.
