Generate real or complex sinusoidal signalsexpand all in pageLibraries: DSP System Toolbox / Signal Operations DSP System Toolbox / Sources DescriptionThe NCO block generates a multichannel real or complex sinusoidalsignal, with independent frequency and phase in each output channel. The amplitude ofthe created signal is always 1. The NCO block supportsreal inputs only. All outputs are real except for the output signal inComplex exponential mode. For more information on how theblock computes the output, see Algorithms.To produce a multichannel output, specify a vector quantity for the Phaseincrement and Phase offset parameters. Bothparameters must have the same length, which defines the number of output channels. Eachelement of each vector is applied to a different output channel.ExamplesGSM Digital Down Converter in SimulinkSimulate steady-state behavior of a fixed-point digital down converter for GSM (Global System for Mobile) baseband conversions. The example model uses blocks from...
