Preliminary specification
PLL stereo decoder and noise blanker
TDA1592
Notes
1. Intermodulation suppression [Beat Frequency Components (BFC)]:
;
;
measured with 91% mono signal; fmod = 10 kHz or 13 kHz; 9% pilot signal.
2. ARI suppression:
measured with 91% stereo signal; fmod = 1 kHz; 9% pilot signal; 5% ARI subcarrier
(fs = 57 kHz; fmod = 23 Hz; AM m = 0.6).
3. Subsidiary Communication Authorization (SCA):
;
measured with 81% mono signal; fmod = 1 kHz; 9% pilot signal; 10% SCA subcarrier (fs = 67 kHz, unmodulated).
4. Adjacent Channel Interference (ACI):
;
;
measured with 90% mono signal; fmod = 1 kHz; 9% pilot signal; 1% spurious signal
(fs = 110 kHz or 186 kHz, unmodulated).
