Abstract
Method and system for determining varying widths of each of a sequence of signal components (marks and spaces) in an incoming digital signal stream and for indicating which mark widths and which space widths fall outside acceptable ranges. A pre-mark and pre-space are added to the front end of the recieved stream for alignment purposes. The width of each signal component (mark or space) is determined and compared with an acceptable range of mark widths or space widths. Each mark or space that lies outside an acceptable range has an indicium associated with this mark or space, indicating this non-compliance. The modified digital signal stream, including the indicia, is re-issued after a selected time delay for subsequent signal processing. A method for measurement or estimation of mark width and space width is presented.
