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.
