Examples
A carrier wave was detected, but outside expected frequency limits and varying in wavelength.
Differential phase-shift keying (DPSK) Differential encoding main Differential phase shift keying (DPSK) is a common form of phase modulation that conveys data by changing the phase of the carrier wave.
For a sine wave modulation, the modulation index is seen to be the ratio of the peak frequency deviation of the carrier wave to the frequency of the modulating sine wave.
For example, in AM radio communication, a continuous wave radio-frequency signal (a sinusoidal carrier wave ) has its amplitude modulated by an audio waveform before transmission.
In transistorized effects, vibrato is produced by mixing an instrument's audio signal with a carrier wave in such a way that generates frequency variations in the sound wave.
In amplitude modulation, the amplitude (signal strength) of the carrier wave is varied in proportion to the waveform being transmitted.
