Ders#3 Açı modülasyonu lineersizliğe dayanıklıdır

1) Dolaylı metod (Indirect method)

– Genlik ve faz bozulmasına sebep olur

Voltage controlled oscillator (Hartley ve Colpitts osilatörlerinde osilasyon frekansı)

* frekans kararlılığı çok iyi değil

FRM (FM)'nin Demodülasyonu

Pratik FM demodülatörleri

Balanced modulators: slope detector / balanced discriminator / ratio detector

Zero-crossed detector

Phase Locked loop (PLL) (Düşük maliyetli ve yüksek performansı )

Açı modülasyonunda karışım (interference)

Başta zaten FM, sonra türevini alıp PM'e geçebiliriz. Bunu yapan filtreye ön vurgulama filtresi denir.

Additive White Gaussian Noise

AWGN: kanal gürültüsü
