8 / 20 page 1996 May 31 8 Philips Semiconductors 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).
