Abstract:
A method for displaying a compacted data signal, comprising the steps of:acquiring a data signal comprising a plurality of data values; computing a compaction table based upon said acquired data signal for each of a plurality of vertical pixel columns of a display device; generating a min/max pair for all data values of said data signal associated with each of said plurality of vertical pixel columns, each said min/max pair stored in a compaction table associated with a respective vertical pixel column; wherein each said compaction table of said plurality of vertical pixel columns further consists of a pair of data points representing a first and a last data value that is associated with a pixel; and wherein a connection between min/max pairs of adjacent vertical pixel columns is made by extending both adjacent min/max pairs and using a middle point of the last and first data values to compute the exact position for connecting the min/max lines; drawing a single vertical line for each said min/max pair; and repeating said acquiring, computing, generating and drawing steps for each data signal acquisition to compute a new compaction table for each said data signal acquisition in order to account for horizontal trigger offset.
