Notes
1. Intermodulation suppression [Beat Frequency Components (BFC)]:
IM2 = -V--V--o--(o--s-(-ps--u-ig--r-ni-o-a--u-l-)s---)(--a(---a-t--t-1---1--k---kH---H-z---z-)--)-- ; fs = ( 2 × 10 kHz) – 19 kHz
IM3 = -V--V--o--(o--s-(-ps--u-ig--r-ni-o-a--u-l-)s---)(--a(---a-t--t-1---1--k---kH---H-z---z-)--)-- ; fs = ( 3 × 13 kHz) – 38 kHz
measured with 91% mono signal; fmod = 10 kHz or 13 kHz; 9% pilot signal.
2. ARI suppression:
α57ARI = V-----o--(--s--p--u-V--r-i-oo--(-u-s-s-i-g-)--n(--a-a--l-)t--(--1-a---t-k---H1----z-k---H-±---z2---)-3-----H----z---)--
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):
α67 = -V--V--o--(o--s-(-ps--u-ig--r-ni-o-a--u-l-)s---)(--a(---a-t--t-1---9--k---kH---H-z---z-)--)-- ; fs = ( 2 × 38 kHz) – 67 kHz
measured with 81% mono signal; fmod = 1 kHz; 9% pilot signal; 10% SCA subcarrier (fs = 67 kHz, unmodulated).
4. Adjacent Channel Interference (ACI):
α114 = V---V--o--(o--s-(-ps--u-ig--r-ni-o-a--u-l-)s---)(--a(---a-t--t-1---4--k---kH---H-z---z-)--)-- ; fs = 110 kHz – ( 3 × 38 kHz)
α190 = V---V--o--(o--s-(-ps--u-ig--r-ni-o-a--u-l-)s---)(--a(---a-t--t-1---4--k---kH---H-z---z-)--)-- ; fs = 186 kHz – ( 5 × 38 kHz)
measured with 90% mono signal; fmod = 1 kHz; 9% pilot signal; 1% spurious signal
(fs = 110 kHz or 186 kHz, unmodulated).
