Operator Library: Signal
The operator converts an image data stream at the input into a signal stream. The input is a binary (1 bit) image stream. For every pixel with value zero at the input a low signal (zero) will be output. For every pixel with value one at the input, a high signal (one) will be output. Image data streams include gaps between pixel. The operator fills these gaps at the output with the last valid input pixel value. See the following figure for explanations.
This operator is excluded from the VisualApplets functional simulation.
