43. 1965_09_15 to 1966_03_14_MRC Engineering Lab Notebook, JVM #08, 1965 September 15-1966 March 14
Scope and Contents
This Note Book contains some miscellaneous logic design and a new transistorized PAS (Peak Amplitude Storage) concept (later implemented in MRC scanners) for capturing and storing the peak-signal level of a response mark from a OMR 'bubble' mark, and secondly, a rigorous (theoretical) trigonometric analysis of sheet skew and side-shift factors during the feeding of an OMR sheet, so as to aid in the understanding of the alignment and clock-timing for controlling the PAS circuitry. There are 56 JPEG-Image files (selected) in the Media Disc (DVD) Folder name: 1965_09_MRC Eng.Notebk JVM#08
