SAWTOOTH_f
Sawtooth generator
Block Screenshot
Contents
Palette
Output:scalar double.
Description
This block is a sawtooth wave generator. The output of the block is described by the equation:
At first event on its activation input, the output increases linearly from 0 with a unitary rate. When the following event occurs, the ouput goes to 0 and begin again to increase until the next event and so on.
The resulting amplitude of the output is equal to the period of event signal. If you want more control on the amplitude or a negative rate, use the Sigbuilder or Curve_f blocks.
