Applications of AM and FM
Amplitude Modulation (AM) and Frequency Modulation (FM) are two fundamental techniques used in analog and digital communication systems. There applications are mentioned below:
Applications of Amplitude Modulation
- AM modulation is commonly used to broadcast radio signals, particularly for AM radio stations.
- AM is extensively utilized in shortwave radio communication, especially for multinational broadcasts.
- AM is utilized in aviation communication systems, including air traffic control and aircraft-to-aircraft communication.
- AM modulation is used in two-way radio communication systems such as Citizen Band (CB) radios, Emergency Communication Systems, and Walkie-Talkies.
Applications of Frequency Modulation
- FM modulation is commonly utilized in commercial radio broadcasting, particularly among FM radio stations.
- FM modulation is used in mobile communication systems, including analog FM-based mobile networks and digital systems.
- FM modulation is widely utilized in wireless microphone systems designed for live events, broadcasting, and recording.
- FM modulation is utilized in radio navigation systems, such as VHF Omni-directional Range (VOR) and Instrument Landing System (ILS), which are used for aircraft navigation.

Difference between Amplitude Modulation and Frequency Modulation
Difference between AM and FM: Amplitude Modulation (AM) and Frequency Modulation (FM) are two essential techniques used in analog communication systems to convey information, such as audio signals, using radio waves. While both approaches accomplish the same purpose of modulating a carrier signal to encode information, they differ in how they modulate the carrier signal and the properties of the modulated signals they generate.
