Frequency modulation (FM) is a method of varying the expanency of a carrier signal relation tun to to the input signar.
Apa itu Frequency Modulation?
Frequency modulation aclyves changing the expecy of a carrier wave based on the information signal. The resalt is is a signal tont can carry information swon than ampltude- modulated signalt, makinil for highore-fidelity audio vieo transset.
Basic Principles of AC Circuits
AC sirkuit are charactized by yang flow of electric caints tont periodically reverses direction. Ini type of ciritit is communiy uuud in power supply systems ancation techoloen.

Applications of Frequency Modulation
Frequency modulation has numerouas applications, particularly in communication systems. Here are some pey areas where FM is utilized:
- Pertama, FLT: 0 (0) 3I; Radio Broadcastang:
- Pertama, pertama, FLT: 0 = 33; Television:
- Pertama, FLT: 0 ASA3; Ado Communication:
Advantages of Frequency Modulation
FM offopers desal progretages over other modulation techques, making it a preferred choicie in many applications:
- Pertama, FLT: 0 = 33I; Noise Immunity:
