Sampled sinusoidal wave#

block

Block appearance in REPEAT VISION#

 The Sampled sinusoidal wave block implements discrete form of sine signal of specified frequency and amplitude. The block allows you to set three different types of discretization, i.e. the time interval between the recorded values of the sinusoidal signal:

  1. Decimation of the fundamental sampling rate of the project - the output signal has a sampling rate N times less than the sampling rate of the project (the inverse of the integration step). Here, N is a given design fundamental sampling rate decimation factor, N ≥ 1.

  2. Sampling period is the interval between time points at which the sine signal values are sampled. The value of the specified sampling period shall be a multiple of the integration step specified in the project.

  3. Sampling frequency - sampling rate of sine signal values. The value of the specified sampling frequency shall be a divider of the sampling frequency specified in the design (the value opposite to the integration step).
