Purpose Generate a continuous or discrete sine wave.

Description The Sine Wave block generates a multichannel real or complex sinusoidal
signal, with independent amplitude, frequency, and phase in each output
channel. A real sinusoidal signal is generated when the
Output complexity
parameter is set to
Real, and is defined by an expression of the type
where A is specified by the
Amplitude parameter, f is specified in hertz by the
Frequency parameter, and φ is specified in radians by the Phase parameter.
A complex exponential signal is generated when the
Output complexity
parameter is set to
Complex, and is defined by an expression of the type
Each parameter value (A, f, φ) for real and complex sinusoids can be a scalar or
length-N vector, where N is the desired number of channels in the output. If at
least one parameter is specified as a length-N vector, scalar values specified for
the other parameters are scalar expanded to length N (i.e., they are applied to
every channel).
For example, specify
•
Amplitude = [123]
•Frequency = [1000 500 250]
•Phase = [0 0 pi/2]
with Output complexity set to Real to generate a three-channel output
containing the real sinusoids below.
