EMPHASIS AND PHASE LINEARITY
When pre-emphasis is detected in the Q-channel
subcode, the digital filter automatically includes a
de-emphasis filter section. When de-emphasis is not
required, a phase compensation filter section controls the
phase of the digital oversampling filter to
≤ ±
1
°
within the
band 0 to 16 kHz. With de-emphasis the filter is not phase
linear.
If the de-emphasis signal is set to be available at V5,
selected via decoder register D, then the de-emphasis
filter is bypassed.
7.7.2
D
IGITAL OVERSAMPLING FILTER
For optimizing performance with an external DAC, the
SAA7326 contains a 2 to 4 times oversampling IIR filter.
The filter specification of the 4 times oversampling filter is
given in Table 3.
These attenuations do not include the sample-and-hold at
the external DAC output or the DAC post filter. When using
the oversampling filter, the output level is scaled
0.5 dB
down to avoid overflow on full-scale sine wave inputs
(0 to 20 kHz).

Filter specification
7.7.3
C
ONCEALMENT
A 1-sample linear interpolator becomes active if a single
sample is flagged as erroneous but cannot be corrected.
The erroneous sample is replaced by a level midway
between the preceding and following samples. Left and
right channels have independent interpolators. If more
than one consecutive non-correctable sample is found, the
last good sample is held. A 1-sample linear interpolation is
then performed before the next good sample (see Fig.11).
In CD-ROM modes (i.e. the external DAC interface is
selected to be in a CD-ROM format) concealment is not
executed.
