Digital modulation methods. In digital modulation, an analog carrier signal is modulated by a discrete signal. Digital modulation methods can be considered as digital-to-analog conversion and the corresponding demodulation or detection as analog-to-digital conversion.
Modulação é o processo no qual a informação transmitida numa comunicação é adicionada a ondas eletromagnéticas. O transmissor adiciona a informação numa onda especial de tal forma que poderá ser recuperada na outra parte através de um processo reverso chamado demodulação . A maioria dos sinais, da forma como são fornecidos pelo ...
Modulation is a technique for impressing information on a carrier wave by varying its amplitude, frequency, phase, or other characteristics. Learn about different forms of modulation, such as amplitude modulation, frequency modulation, phase modulation, and digital modulation.

Modulation Method Classification. Modulation is the process of converting data into electrical signals optimized for transmission. Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method. Analog modulation is typically used for AM, FM radio, and short-wave ...
Amplitude modulation ( AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in ...
