Sinusoidal function

| Vector | C | ST |
in the palette on the schematic
The block is vectorized. The block returns the output value calculated by the following algorithm:

where a, ω, f – amplitude, circular frequency (rad/s) and phase (rad), x(t), y(t) – input and output signals.
Additionally, depending on the block settings, it can return a cosine value

or tangent value

Inputs

  • input - the port for the function argument input.

Outputs

  • output - the port of the function value.

Properties

  • Amplitude, in the formula a·sin[w·x(t) + f] – the coefficient a.
  • Frequency – coefficient ω.
  • Phase – coefficient f.
Properties can be vectors whose dimensions must be equal to the dimension of the input, in this case, the output will also be a vector.

Parameters

none

Note:
  1. By default, this block implements sinusoidal transformation of the input signal (scalar or vector) with coefficients a=1, ω=1, f=0.
  2. Named properties can be set as local model variables (or submodels) in a programming language script, as global project signals using the Tools → Signals main menu item, or as external project signals using an attachable signal database.
