What is FM (Frequency Modulated)?

Frequency modulation (FM) is the encoding of data in a transporter wave by differing the instantaneous recurrence of the wave. Frequency modulation is generally utilized for FM radio broadcasting. It is likewise utilized in telemetry, radar. A benefit of recurrence modulation is that it has a larger signal-to-noise ratio and in this manner rejects radio recurrence interference better than an equivalent power amplitude modulation (AM) signal.
