1. Signal monitoring and display apparatus including a plurality of element lines arranged in at least two groups and respectively carrying signals representative of the current states of elements to be monitored;

  • means for producing first timing signals at a first frequency and second timing signals at a second frequency which is a submultiple of said first frequency;

    first parallel to serial converter means including a first parallel to serial converter module for each separate group of element lines, each said first module having a group of gating means respectively corresponding to and connected to a different one of the element lines, and scanning means responsive to the first signals to scan said group of gating means produce a first module output signal having a succession of elemental components respectively representing the states of the elements of the associated line group; and

    second parallel to serial converter means having a data output line and including at least one second parallel to serial converter module having a group of gating means respectively corresponding to and connected to receive a different one of the first module output signals and scanning means responsive to the second signals to scan the group of gating means to produce on said data output line a data output signal containing as serial components the elemental components arranged in order from each of the groups in succession and said timing signals; and

    a display device responsive to the data output signal of the second parallel to serial converter means data to provide a visual representation of the individual states of the elements.
