O que (quem) é outphasing modulation - definição

WIKIMEDIA DISAMBIGUATION PAGE
Modulation factor; Modulation depth; Modulation index (disambiguation)

Modulation         
  • A low-frequency message signal (top) may be carried by an AM or FM radio wave.
  • Categorization for signal modulation based on data and carrier types
  • [[Waterfall plot]] of a 146.52 MHz radio carrier, with amplitude modulation by a 1,000 Hz sinusoid. Two strong sidebands at + and - 1 kHz from the carrier frequency are shown.
  •  A carrier, frequency modulated by a 1,000 Hz sinusoid. The [[modulation index]] has been adjusted to around 2.4, so the carrier frequency has small amplitude. Several strong sidebands are apparent; in principle an infinite number are produced in FM but the higher-order sidebands are of negligible magnitude.

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. For example, the modulation signal might be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal representing a sequence of binary digits, a bitstream from a computer.

Modulation index

The modulation index (or modulation depth) of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level. It is defined differently in each modulation scheme.

  • Amplitude modulation index
  • Frequency modulation index
  • Phase modulation index
