This is known as Amplitude Modulation (AM). Figure 3-2. An amplitude modulated signal. The demodulation process for AM where the radio frequency signal is converted into an audio frequency signal is ...

it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually no cost. Demodulation of frequency modulation (FM) signals can be done in many ways. There are FM ...

First, the modulation and demodulation processes use two signals in quadrature with one another. The DSP calculations call for two quadrature signals if the phase and amplitude are to be preserved ...

Figure 12 shows the hard-decision approach to demodulation in this case. As in the case of two-level amplitude modulation, after acquiring brightness values for all pixels, we performed a ...

High-capacity modems are implemented with higher-order modulation ... and excellent demodulation accuracy (with 0.1-dB amplitude and 0.5° phase accuracy). The highly balanced design provides ...

In television broadcasting, the picture is carried by amplitude modulation ... response of this particular demodulator is limited to 800kHz in the I and Q channels. In television broadcasting, audio ...
