Block Name: Pulse
Code File Location: VisualSim/actor/lib/Pulse
o Produce a pulse with a shape specified by the parameters.
Produce a pulse with a shape specified by the parameters. The values parameter contains an Array, which specifies the sequence of values to produce at the output. The indexes parameter contains an array of integers, which specifies when those values should be produced. The array in the indexes parameter must have the same length as that in the values parameter or an exception will be thrown. Also, the indexes array must be increasing and non-negative, or an exception will be thrown when it is set.
Eventually, this block supports a zero (of the same type as the values) whenever the iteration count does not match an index in indexes.
The default for the values parameter is an integer vector of form {1, 0}. The default indexes array is {0, 1}. Thus, the default output sequence will be 1, 0, 0, ...
However, the Pulse block has a repeat parameter. When set to true, the defined sequence is repeated indefinitely. Otherwise, the default sequence of zero values result.
The type of the output can be any token type. This type is inferred from the element type of the values parameter.
Refer Pulse Demo Model.
