Description

This block is a sine wave generator and its output is defined by the equation:

You can adjust:

• The magnitude * `M`* with the Magnitude parameter.
• The frequency * `F`* in radians/second with the Frequency parameter.
• The initial phase * `P`* in radians with the Phase parameter.

Data types

• Output: Scalar double.

Dialog box

• Magnitude A scalar. The magnitude M. Properties : Type ‘vec’ of size 1.
• Frequency A scalar. The frequency in radians/secondes. Properties : Type ‘vec’ of size 1.
• Phase A scalar. The phase P in radians. Properties : Type ‘vec’ of size 1.

Default properties

• always active: yes
• direct-feedthrough: no
• zero-crossing: no
• mode: no
• regular outputs: - port 1 : size [1,1] / type 1
• number/sizes of activation inputs: 0
• number/sizes of activation outputs: 0
• continuous-time state: no
• discrete-time state: no
• object discrete-time state: no
• name of computational function: gensin

Example

This diagram shows the output of the block GENSIN_f for an amplitude value of 1.2 and an initial phase offset of 90°. Open this example in Xcos
