Notes

1. The FM level information V50-3 is analog-to-digital converted with 4 bits.

2. The AM level information V49-4 is analog-to-digital converted with 4 bits.

3. The multi-path information V40-4 is analog-to-digital converted with 3 bits covering an IF2 amplitude modulation range

m ≤ 0.6; fmod = 20 kHz.
