Sine wave generator

Block Screenshot


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/seconds.

    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:
