How do you find the amplitude spectrum of a signal?
The shape of the amplitude spectrum is determined by the function sin( f ) f π τ π τ . the single rectangular pulse of width τ contains all frequencies between 0 and ∞. the relative amplitudes (ignoring the overall amplitude factor) of these frequencies is given by the function sin( f ) f π τ π τ .
How do you find the spectrum of an FM signal?
Start. The modulation index ß is the ratio of the maximum frequency deviation of the carrier to the frequency of the sinewave modulating signal. The Bessel function values at the resulting modulation index determine the spectrum of the FM signal.
What is the spectrum of FM?
The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf. AM radio which limits the upper frequency to 5 kHz).
What is amplitude modulation spectrum?
Amplitude modulation spectrum of two sine waves, carrier C and modulator M, showing the addition of a pair of sidebands, C + M and C - M, around the carrier. The amplitude of the modulating signal controls the amplitude of the carrier frequency, as well as that of the sidebands, in the resulting spectrum.
