FM1 and FM2 demodulators
Measurements with FM IF input signals of 5.5 MHz and 5.74 MHz with V_{i IF (rms)} = 10 mV (f_mod = 1 kHz, deviation
∆f = ± 50 kHz) at pins 15 and 19 without ceramic filters, R_S = 50 Ω.
De-emphasis 50 µs and V₅ = V_P (B/G standard). Q_L-factor = 11 for resonant circuits at pins 6-7 and 10-11.
