Description

It is a discrete block. The block outputs a periodic scalar piecewise constant signal. Signal begin at Initial State value. The output is incremented when block received an event on its activation input until output reaches the Upper Limit parameter value. At this time the output is reset to 0. For a periodic event input, the output is a quantized sawtooth signal.

Data type

• Output: scalar double.

Parameters

• Initial State

  Scalar. Initial discrete state.

  Properties : Type 'vec' of size 1

• Upper Limit (positive number)

  Scalar. Number of required step.

  Properties : Type 'vec' of size 1

Default properties

• always active: no

• direct-feedthrough: no

• zero-crossing: no

• mode: no

• regular outputs:

  - port 1 : size [1,1] / type 1

• number/sizes of activation inputs: 1

• number/sizes of activation outputs: 0

• continuous-time state: no

• discrete-time state: yes

• object discrete-time state: no

• name of computational function: modulo_count

Example

This diagram shows the Modulo_count usage as a quantized sawtooth generator application.
