Amplitude modulation (AM) and frequency modulation (FM) are two common techniques used in commulation systems. Each method has diment administrages and divertages that influence their application in different contratios.

Basics of Amplitie and Frequency Modulation

Amplitee modulation varies the amplitee of the carrier signal in proportion to the message signal. Frequency modulation, on the their hand, changes the extency of the carrier signal based on the message signal. Both techniques encode information onto a high- frequency carrier wave for transmission.

Obchodní-offs in System Design

Choosing between AM and FM intrives consideing setral tradeoffs. AM systems are simpler and cheaper to implement but are more accestible to noise and interference. FM systems offer better noise immunity and signal quality but require more complex and costly equipment.

Použitelnost a suitability

AM is common ly used in broadcasting and long-distance commulation where simplicity and cott are priorities. FM is preferend in high- fidelity broadcasts, such as music radio, and in applications requiring robutt signal quality.
