Operator Library: Signal
The operator generates a signal pulse for each input pixel with value 1. The operator input is a binary (1 bit) image stream. If a pixel with value one is present at the input of the operator, the operator will generate a signal pulse of one clock cycle. Keep in mind that image data streams include gaps between pixels. During a gap period, the operator does not generate output pulses. If you rather like to convert the last input binary pixel value into a signal, use operator PixelToSignal instead.
This operator is excluded from the VisualApplets functional simulation.
