Frequency modulation (FM) is a methodod of varying the currency of a carrier signal in relation to tho the amplitee of the input signal. This technique is widely used in various applications, including radio broadcasting, television, and data transmission. Unstanding FM in alternating curgent (AC) conclusits is essential for studits and teors in te field of Televics and commulation.

Co je to často Modulation?

Frequency modulation involves changing thee frequency of a carrier wave based on tha e information signal. Thee result is a signal that can carry more information than amplitudemodulated signals, making it ideal for high- fidelity audio and data transmission.

How Frequency Modulation Works in AC Circuits

In an AC obvody, currency modulation can be affected by varying the input signal that accors thee carrier wave. Te modulation index, which determinates the extent of extency variation, plays a curcial role in this process.

Modulation-efex

Te modulation index (β) is definied as the ratio of the frequency deviation (Δf) to te frequency of the modulating signal (fm). It can be expressed discredially as:

  • β = Δf / fm
