A system for analysing and annotating time-varying signals comprises a substrate for carrying the time-varying signal in printed form, a printer for printing the time-varying signal over the substrate and a reading and writing device for reading a local background pattern of the substrate and writing on the substrate, the reading and writing device enabling the position of annotations on the substrate to be determined. Local portions of the background pattern on the substrate uniquely identify a location of the background pattern over the substrate. This enables the position of annotations on the substrate which relate to portions of the signal to be determined. This enables annotations written on the printed plot to be stored digitally. The locations of the markings which define the annotations enable not only the annotations themselves to be recorded, but also the parts of the signal to which they relate.
A substrate for carrying a printed time-varying signal, wherein the substrate carries a background pattern, in which local portions of the background pattern uniquely identify a location of the background pattern over the substrate, thereby enabling the position of annotations on the substrate which relate to portions of the signal to be determined.
A system for analysing and annotating time-varying signals, comprising:
A method of printing time-varying signals, comprising printing the time-varying signal onto a substrate which carries a background pattern, in which local portions of the background pattern uniquely identify a location of the background pattern over the substrate.
A computer program for collating data relating to the analysis of a time-varying signal, the computer program adapted to:
