Modulation
The modulation block converts the information signal bit stream into in-phase (I) and quadrature-phase (Q) data components. This block typically also involves pulse shaping to minimize intersymbol interference and reduce bandwidth.
Depending on the type of information signal and the particular transmission medium, different modulation techniques are employed. For example, in amplitude modulation (AM), the information is represented by amplitude variations of the carrier signal.
The Modulation Toolkit supports the following types of analog modulation:
The Modulation Toolkit also supports the following types of digital modulation:
