These complex variations in frequency and amplitude are exactly what we find in audio signals, and as you know, frequency modulation is widely used to transmit sound information. In this article, we’ll convert a sound file into a typical Scilab data array and then perform frequency modulation using this real-life data as the baseband signal.

The modulating audio signal will cause the frequency of the RF “carrier” signal to either increase slightly or decrease slightly, as the AC audio signal changes with time. If the AC audio signal is negative, the RF frequency will be slightly less than the “carrier frequency” of 101.1 MHz. If

1 Answer Active Oldest Score 1 Algorithm To encode a signal x m in a carrier with frequency f c, we proceed as: y ( t) = cos ( ϕ ( t)), ϕ ( t) = 2 π ⋅ ( f c t + f Δ ∫ 0 t x m ( τ) d τ) where f Δ controls the maximum deviation of y 's instantaneous frequency from f c (effectively its bandwidth, but not in strict Fourier sense).

In frequency modulation, the message to be transmitted is converted into an analog signal. This analog signal or audio message is then passed through a carrier wave whose frequency varies concerning time. The result is a modulated RF signal receiving and demodulating at the receiver to recover the original audio message.

Frequency Modulation (FM) Definition: A category of angle modulation in which the frequency of the carrier wave is changed according to the amplitude of the message signal is known as frequency modulation. It is abbreviated as FM and is a widely used analog modulation technique.

The Bandwidthof anFM Signal The following formula, known as Carson’sruleis often used as an estimate of the FM signal bandwidth: BT = 2(∆f +fm) Hz (16) where ∆f is the peak frequency deviation and fm is the maximum baseband message frequency component. Example Commercial FM signals use a peak frequency deviation of ∆f = 75 kHz and a maximum
