Description

The Saturation block imposes upper and lower bounds on a signal. When the input signal is within the range specified by the Lower limit and Upper limit parameters, the input signal passes through unchanged. When the input signal is outside these bounds, the signal is clipped to the upper or lower bound. When the Lower limit and Upper limit parameters are set to the same value, the block outputs that value.

Parameters

• Upper limit

  Specify the upper bound on the input signal. When the input signal to the Saturation block is above this value, the output of the block is clipped to this value.

  Properties : Type 'vec' of size 1

• Lower limit

  Specify the lower bound on the input signal. When the input signal to the Saturation block is below this value, the output of the block is clipped to this value.

  Properties : Type 'vec' of size 1

• Zero crossing

  Select to enable zero crossing detection.

  Properties : Type 'vec' of size 1

Default properties
