AM Spectrum (Sidebands) Calculator
This calculator predicts the spectrum (sideband levels) due to AM (Amplitude Modulation). The results are valid for sinewave modulation only. Applications include calibration of modulators.
It should be noted that a real system with non sinusoidal modulation, or with distortion in the modulator, will show harmonic sidebands in addition to the fundamental ones.
The example shown here has 50% modulation and several distortion products are visible.
Enter a value for P, the percentage of modulation.
