Definitions

  • a signal indicating the end of the column is generated on line 29 which signal is fed on line 50 to shift register 20 and which is operative to parallel shift the column of hits out of the shift register to display panel 23.
  • the signal on column line 29 is also fed to line 31 where it activates counter 21, the outputs of which selectively actuate the output conductors of panel pulse generator 22. While in an actual embodiment, counter 21 would have eight output lines connected to the eight conductors at panel 22, for ease of illustration a single output line 51 is illustrated.
  • FIG. 2 illustrates the A to D level converter 5 of FIG. 1 in greater detail.
  • the outputs of vidicon 4 are fed to level detectors 80, 81, 82 and 83 which may, for instance, be Schmitt triggers.
  • the output of the level detectors are arranged to be in the one state until the input signal to the detector exceeds the predetermined amplitude level at which time the output changes to the zero state.
  • Zero state output line 84 from level detector 80 and one state output line 85 from level detector 81 are fed to AND gate 91.
  • zero state output line 86 of level detector 81 and one state output line 87 of level detector 82 are fed to AND gate 92 and zero output line 88 of level detector 82 and one state output line 99 of level detector 83 are fed to AND gate 93.
  • Output lines 37, 38, and 39 from AND gate 91, 92 and 93 respectively, are fed to row and column couplers 6, 8 and 10 and zero state output line from level detector 83 is fed to row and column coupler 12 as shown in FIG. 1.
